Explanation:
Add 9 and 3 which is 9 + 3
THEN multiply by 6 which is 6(9 + 3)
I put parentheses because it's sayings to add first and then multiply!
select all values that make the equation true 2(x-8)=x+5x
x= -4
x= -16
x= -2
x= -0
Answer:
x = -4
Step-by-step explanation:
2(x-8)=x+5x
Combine like terms
2(x-8) = 6x
Divide by 2
2(x-8)/2 = 6x/2
x-8 = 3x
Subtract x from each side
x-8-x = 3x-x
-8 = 2x
Divide by 2
-8/2 = 2x/2
-4 =x
Can someone help me!! what is the smallest positive counterclockwise roation if the point is rotated at 272 degrees clockwise
Given:
The point is rotated at 272 degrees clockwise.
To find:
The smallest positive counterclockwise rotation for the given clockwise rotation.
Step-by-step explanation:
Clockwise rotation = 272°
We need to subtract the given clockwise rotation from 360° to get the smallest positive counterclockwise rotation, because one complete circle is 360°.
Counterclockwise rotation = 360° - Clockwise rotation
= 360° - 272°
= 88°
Therefore, the smallest positive counterclockwise rotation is 88°.

Which statements below are TRUE about perpendicular lines? I. Perpendicular lines intersect II. Perpendicular lines create right angles III. Perpendicular lines are collinear IV. Perpendicular lines never intersect V. Perpendicular lines are coplanar
Answer:
Step-by-step explanation:
Two lines are perpendicular to each other if they both intersects and the two lines are inclined at angle 90°
Since they are inclined at 90° to each other, hence they create right angles.
The lines can also lines on the same plane to form a right angles. This are called coplanar lines.
From the above explanation, the following are true;
I) Perpendicular lines intersect
II) Perpendicular lines create right angles
V) Perpendicular lines are coplanar
They are not collinear because they can't lie on the same straight line. Collinear lines are known to lie on the same straight line.
At noon, the minute and the hour hands of a clock overlap. In how long will they again overlap?
Answer:
In an hour and 5 minutes
(or 60 seconds but it will only overlap for a second)
Explanation:
After 60 minutes it will be an hour and the clock will show 1o'clock, after 5 minutes, the minute hand will be at the "1" so they will over lap at 1:05
Answer: 5.45

y=10x+35
so for 4 yoga classes, it is $75
so for 8 yoga classes, it is $115
so for 12 yoga classes, it is $155
Step-by-step explanation:
So 35 is only a one-time payment and it is over so we just add 35, but $10 is the rate of change depending on how much yoga class you have been into so the equation will be y=10x+35
Explanation for 4 yoga classes: y=10(4)+35 which is 75
Explanation for 8 yoga classes: y=10(8)+35 which is 115
Explanation for 12 yoga classes: y=10(12)+35 which is 155

-17 = -7c + 4
Answer: c = 3
Step-by-step explanation:
Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.
Step 1: Subtract 4 from both sides.
-17 - 4 = -7c
Step 2: Simplify -17 - 4 to -21.
-21 = 7c
Step 3: Divide both sides by -7.
[tex]\frac{-21}{-7}[/tex] = c
Step 4: Two negatives make a positive.
[tex]\frac{21}{7}[/tex] = c
Step 5: Simplify [tex]\frac{21}{7}[/tex] to 3.
3 = c
Step 6: Switch sides.
c = 3

Alvin and Simon shared £540 in the ratio 4:5. Alvin gave half of his share to Theo. Simon gave a tenth of his share to Theo. What fraction of the £540 did Theo receive.
Answer:
[tex]\frac{5}{18}[/tex]
Step-by-step explanation:
sum the parts of the ratio, 4 + 5 = 9 parts
Divide the amount by 9 to find the value of one part of the ratio
£540 ÷ 9 = £60 ← value of 1 part of the ratio , thus
4 parts = 4 × £60 = £240 ← Alvin's share
5 parts = 5 × £60 = £300 ← Simon's share
[tex]\frac{1}{2}[/tex] × £240 = £120
[tex]\frac{1}{10}[/tex] × £300 = £30
Theo receives £120 + £30 = £150 , which as a fraction is
[tex]\frac{150}{540}[/tex] ( divide numerator/ denominator by 30 )
= [tex]\frac{5}{18}[/tex] ← in simplest form
write 125 as a repeated multplication of 5 then write the power
Answer:
5×5×5=5³
Step-by-step explanation:
Answer:
A power, or exponent, represents how many times the term, in this case 5, is multiplied by itself. So multiply 5 by itself until you get 125. Then write your answer as 5ˣ where x is the number of times you multiplied 5 by itself.

Convert the scientific notation into a standard form number,
1.23 x 10-5
Step-by-step explanation:
[tex]a^{-n}=\dfrac{1}{a^n}\\\\\text{therefore}\ 10^{-5}=\dfrac{1}{10^5}=\dfrac{1}{100000}=0.00001\\\\1.23\cdot10^{-5}=1.23\cdot0.00001=0.0000123[/tex]
[tex]a\cdot10^{-n}[/tex] - move the decimal point n place to the left
[tex]a\cdot10^n[/tex] - move the decimal point n place to the right
Examples:
[tex]1.2\cdot10^5=1\underbrace{20000}_{5\to}=120,000\\\\1.2\cdot10^{-5}=0\underbrace{.00001}_{\leftarrow5}2=0.000012[/tex]
A researcher found that 55% of families in the United States have one child under the age of 21, 22% have two children under the age of 21, 15% have three children under the age of 21, 5% have 4 children under the age of 21and 3% have 5 or more children under the age of 21. If a family is selected at random, what is the probability the family has 1 or 3 children under the age of 21?
Answer:
67% or 0.67
Step-by-step explanation:
Given that:
P(1 child under age 21) = 55%
P(2 children under age 21) = 22%
P(3 children under age 21) = 15%
P(4 children under age 21) = 5%
P(5 or more children under age 21) = 3%
If a family is selected at random, what is the probability the family has 1 or 3 children under the age of 21?
P(1 or 3 children under age 21):
Either the selected family has 1 child under 21 years of age OR the selected family has 3 children under 21 years of age ;
P(1 child under age 21) + P(3 children under age 21)
= 55% + 15%
= 67% = 0.67
What is the slope between point A (-9, 4) and B ( 3, -2)
I NEED HELP ASAP
a)1/2
b)-1/2
c)2
d)-2
e)3/2
Slope can be calculated using the formula: m= [tex]\frac{y2 - y1}{x2 - x1}[/tex]
y1/x1 represents the first number in the bracket
y2/x2 represents the second number in the bracket
Calculation
m = [tex]\frac{y2 - y1}{x2 - x1}[/tex]
m =[tex]\frac{4 - (-2)}{(-9)-3}[/tex]
m= 6/-12
m= -0.5 or -1/2
Therefore, the answer is B.

Is y=x+3.75 proportional
Answer:
NO
Step-by-step explanation:
if we plug in 1 = x, we get 4.75 = y. If this is proportional, then y/x will be the same in each scenario.
Let's plug in 2 = x to get y = 5.75. 5.75/2 = 2.875 DOES NOT EQUAL 4.75/1 = 4.75.
That means that the relationship is NOT proportional.
The easier way to tell is to see that there is a number being added, so it can't be a proportional relationship.
Hope this helps and pls do mark me brainliest if you can:)
Answer: No
Step-by-step explanation:
The equal y=x+3.75 is expressed in slope intercept form meaning it doesn't fit the proportional equation which is y=kx and k is the slope.
Because of the y-intercept of the line it makes it not proportional .

Evan earned $26 for 4 hours of babysitting.
What equation can be used to model his
total earnings y for babysitting x hours?
Then graph the equation on the coordinate
plane. What is the unit rate? How is that
represented on the graph?
The equation y = 6.5x will represent the situation and the unit rate will be $6.5/hour.
How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
Given that,
Evan earned $26 for 4 hours of babysitting.
If total earnings y for babysitting x hours then,
y = (26/4)x ⇒ y = 6.5x will be the equation.
The unit rate of the function is y/x = $6.5/hour.
Hence "The equation y = 6.5x will represent the situation and the unit rate will be $6.5/hour".
