Answer:
$7.50
Step-by-step explanation:
Let the price of one sandwich = x
Hence,
The total cost = Cost of 5 identical sandwiches + 1 bag of chips
The bag of chips costs $1.25, and the entire order costs $38.75.
Hence:
$38.75 = 5x + $1.25
5x = $38.75 - $1.25
5x = $37.50
x = $37.50/5
x = $7.50
Therefore, the price of one sandwich is $7.50

Find rhe x- and y- intercerpts of the following relationships.(There may be more then one)
[tex]3x^{2} + 2y^2 = 24[/tex]
Answer:
see explanation
Step-by-step explanation:
Given
3x² + 2y² = 24
To find the x- intercepts , let y = 0 in the equation and solve for x
3x² + 2(0)² = 24, that is
3x² = 24 ( divide both sides by 3 )
x² = 8 ( take the square root of both sides )
x = ± [tex]\sqrt{8}[/tex] = ± 2[tex]\sqrt{2}[/tex] ← x- intercepts
To find the y- intercepts. let x = 0 in the equation and solve for y
3(0)² + 2y² = 24 , that is
2y² = 24 ( divide both sides by 2 )
y² = 12 ( take the square root of both sides )
y = ± [tex]\sqrt{12}[/tex] = ± 2[tex]\sqrt{3}[/tex] ← y- intercepts
Write the equation of a line perpendicular to y =
3
x-3 and whose y-intercept is (0,12).
Answer:
y=-1/3x+12
Step-by-step explanation:
The slope of a line that is perpendicular to another is the negative reciprocal of the first. The slope of the line is 3 so the negative reciprocal will be -1/3.
Using the point-slope formula we can solve for the equation of a line with a slope of -1/3 and a point of (0,12).
The point slope formula is
y-y1=m(x-x1).
y-12=-1/3(x-0) -------------->Distribute: y-12=-1/3x ---------------> Isolate the y by moving the 12 to the other side. y=-1/3x+12

We are asked to turn this fraction ([tex]\frac{9}{10}[/tex]) into an equivalent fraction, but with a denominator of 100.
[tex]\frac{9 <- Numerator}{10<-Denominator}[/tex]
All we have to do is multiply the numerator and denominator by 10, since 10 times 10 equals 100.
[tex]\frac{9}{10} * \frac{10}{10} = \frac{90}{100}[/tex]
The answer is:
[tex]\frac{90}{100}[/tex]

Laquan will give each guest at his party ¹⁄₂ of a cake. How many cakes should he order if 17 people are attending his party?
Answer:
9 cakes
Step-by-step explanation:
If each of the 17 people will eat 1/2 of a cake, you would 17*1/2 cakes. This is 17/2, or 8.5. You cannot usually order 8.5 cakes, so you would round up. 9 cakes.
16. An experiment is carried out to determine how different pH values of soil will affect the growth of tomato plants. In this
experiment, the independent variable could be the
1. Type of the tomato plant
2. Amount of soil provided
3. Colour the of tomato
4. Light intensity
Step-by-step explanation:
2. Amount of soil provided.
In order to give different pH values of the soil, the amount of soil can directly affect this independent variable.
Mr. Gonzalez drove 30 miles in March. He drove 5 times as many miles in March as he did in January. He drove 2 times as many miles in February as he did in January. How many miles did Mr. Gonzalez drive in February?
Step-by-step explanation:
Given information :
Mr. Gonzalez drove 30 miles in March. In January, she drove 1/5 as much as in March.
30 ÷ 5 = 6 miles in January
in JanuaryShe drove 2 times as many miles in February as she did in January. In January, she drove 30 miles.
6 x 2 = 12 miles in February
When 11 is subtracted from twice a number, the square root of the result is 4. Find the number.
Answer: I think 27/2
Explanation:
Let number = x:
√(2x - 11) = 4
Now to get x, we undo the square root by squaring both sides:
[√(2x - 11)]² = 4²
(2x - 11) = 16
2x = 27
x = 27 / 2

Cell phone plan a cost 70 per month but gives you a free 500 dollar phone plan b coat 50 dollors but has no phone. How long would it take them to reach the same proce
Answer:
Number of month = 25 month
Step-by-step explanation:
Given:
Plan A $70 per month and $500 phone cost
Plan B $50 per month No phone
Assume;
Number of month = x
So,
50x + 500 = 70x
20x = 500
x = 25
Number of month = 25 month
Fred's art project involves a series of parallel stripes. If he starts by drawing the line 8x+2y=7, select all the equations that could represent lines that could also be drawn for his art project.
Options:
A. [tex]y-1 = 4(x + 8)[/tex]
B. [tex]y = -4x + 15[/tex]
C. [tex]16x + 4y = 9[/tex]
D. [tex]y=-4x[/tex]
E. [tex]4x + 2y = 3[/tex]
Answer:
B. [tex]y = -4x + 15[/tex]
C. [tex]16x + 4y = 9[/tex]
D. [tex]y=-4x[/tex]
Step-by-step explanation:
Given
[tex]8x + 2y = 7[/tex]
Required
Select all equations that could be used.
Equation that could be used in place of [tex]8x + 2y = 7[/tex] must have the same slope.
Calculating the slope of [tex]8x + 2y = 7[/tex]
Make y the subject
[tex]2y = 7 - 8x[/tex]
[tex]y = \frac{7}{2} - \frac{8x}{2}[/tex]
[tex]y = \frac{7}{2} - 4x[/tex]
[tex]y = - 4x + \frac{7}{2}[/tex]
Using y = mx + b
Where
[tex]m = slope[/tex]
The slope is -4
Option A.
[tex]y-1 = 4(x + 8)[/tex]
Open bracket
[tex]y - 1=4x + 32[/tex]
Collect Like Terms
[tex]y - 4x = 32 + 1[/tex]
[tex]y - 4x = 33[/tex]
Make y the subject
[tex]y = 4x + 33[/tex]
The slope of this line is 4;
Hence, it can not be used.
Option B.
[tex]y = -4x + 15[/tex]
The slope of this line is -4;
Hence, it can be used.
Option C.
[tex]16x + 4y = 9[/tex]
Solve for4y
[tex]4y=9 - 16x[/tex]
Solve for y
[tex]\frac{4y}{4} =\frac{9}{4} - \frac{16x}{4}[/tex]
[tex]y =\frac{9}{4} - 4x[/tex]
[tex]y = - 4x + \frac{9}{4}[/tex]
The slope of this line is -4;
Hence, it can be used.
D. [tex]y=-4x[/tex]
The slope of this line is -4;
Hence, it can be used.
E. [tex]4x + 2y = 3[/tex]
Solve for 2y
[tex]2y = 3 - 4x[/tex]
Solve for y
[tex]\frac{2y}{2} = \frac{3}{2} - \frac{4x}{2}[/tex]
[tex]y = \frac{3}{2} - 2x[/tex]
The slope of this line is -2;
Hence, it can not be used.
From the calculations above, equations B, C and D are equivalent
Carlos is picking 6/384 apples. Mateo is picking oranges of 10. How much did Mateo pick?
Question might be incomplete or incorrect so we'd have to assume Mateo took apples
Answer:
5/189 apples
Step-by-step explanation:
If Carlos picks 6/384 apples then there must be 384 apples available to pick from. Amount of apples left after Carlos picks =384-6=378 apples
If Mateo picks 10 apples after Carlos then how much apples Mateo has taken would depend on the number of apples available, hence the fraction of apples Mateo has taken = 10/378
Reduce to lowest terms to get 5/189 apples
WHAT IS X???
1.2/0.96 = 3.0/x
Answer:
x= 2.4
Step-by-step explanation:
Answer:
2.4 or 12/5
Step-by-step explanation:
1.2/0.96=3/x
convert the decimal into a fraction---- 6/5 /0.96= 3/x
Simplify the complex fraction-----5/4 = 3/x
simplify the equation using cross-mulitpication----- 5 x = 12
divide both sides of the equation by 5--- x= 12/5
Check if the solution is in the defined range
Alternitive form:
x=2 2/5, x =2.4

Answer:
4 miles in 1/3 houra
Step-by-step explanation:
Which speed is the fastest? Group of answer choices LaTeX:
The formula for speed =
Distance (miles) / Time (hours)
A) 4 miles in 1/3 hours
= 4 / 1/3
= 4 ÷ 1/3
= 4 × 3
= 12 miles per hour
B)1/3 miles in 4 hours
=1/3 miles/4 hours
= 1/3 ÷ 4 miles per hour
= 1/3 × 1/4 miles per hour
= 1/12 miles per hour
C) 1/2 miles in 3 hours
= 1/2 miles / 3 hours
= 1/2 ÷ 3
= 1/2 × 1/3
= 1/6 miles per hour
The fastest speed is A, 4 miles in 1/3 houra
