What is the solution for the equation
(10-5y|= 20
Answer:
y = -2
Step-by-step explanation:
To find the answer, use property of inequality:
10-5y=20
Undo the +10, so - 10 to the other side
so,
-5y= 10, or -5xY.
so divide by -5 from both sides:
10/-5=-2
so, the remain of the equation is:
y = -2
which is the answer

2 software packages + 5 months of gameplay = $130
$40 + 5 months of gameplay = $130
5 months of gameplay = $90
1 month of gameplay = $18
Answer:
18 dollars
Step-by-step explanation:
m = months of game play
130 = (20 + 1m) + (20 + 4m)
130 = 40 + 5m
90 = 5m
18 = m

Nicholas wrote the steps below to
simplify the fraction _
20
30. Melanie divided the numerator and
denominator of _
20
30 by 2 to write the fraction in the simplest form.
Explain and correct the error that each student made.
Answer:
He does not divide the numerator and the denominator by the same number. Nicholas divides 20 by 5 and 30 by 6. He ought to have divided 30 by 5 as well and then simplified.
P.S. Nicholas should have just divided both 20 and 30 by 10 to simplify in one step
Need help finding the slope and how to graph it.
Answer:
The slope is 2/3
Step-by-step explanation:
you need to use the equation y=rise over run, so the equation would be 2-4 over -2-1 and that would equal 2/3 and to graph you just need to find the y-intercept and put it together with the slope y=2/3+b

Put the following equation of a line into slope-intercept form, simplifying all
fractions.
6x + 4y = 8
Answer:
[tex]y=-\frac{3}{2}+2[/tex]
Step-by-step explanation:
First subtract 6 from both sides:
[tex]6x+4y=8[/tex]
-6 -6
New equation becomes:
[tex]4y-6=8[/tex]
Divide all by 4:
4 -6 8

4 4 4
[tex]y=-\frac{3}{2}+2[/tex]
Hence, the final answer is [tex]y=-\frac{3}{2}+2[/tex]
Devi’s dog weighs 4 times as much as her cat. Her dog also weighs 13 pounds more than the cat. How much does each pet weight?
Answer: The cat's weight is 4.33 pounds
• The dog's weight is 17.32 pounds.
Step-by-step explanation:
Let the weight of the cat be represented by a.
Devi’s dog weighs 4 times as much as her cat. This can be written as:
= 4 × a
= 4a
Her dog also weighs 13 pounds more than the cat. This can be written as:
= a + 13
We then equate both equations. This will be:
4a = a + 13
4a - a = 13
3a = 13
a = 13/3
a = 4.33 pounds
The cats weight is 4.33 pounds
Since the dog's weight = 4a = 4 × 4.33 = 17.32 pounds
Dan invests £13000 into his bank account. He receives 4,7% per year simple interest. How much will Dan have after 6 years? Give your answer to the nearest penny where appropriate,
Simple interest formula:
Total = start value x (1 + (rate x time))
Total = 13,000 x (1 + (0.047 x 6))
Total = 13000 x 1.282
Total = £16,666

What is the greatest common factor shared by 9 and 57
Answer:
es 3
Step-by-step explanation:
Para encontrar el mcd de 9 y 57:
Los factores de 9 son 9, 3, 1.
Los factores de 57 son 57, 19, 3, 1.
Los factores en común de 9 y 57 son 3, 1, los cuales intersectan los dos conjuntos arriba.
En la intersección de los factores de 9 ∩ factores de 57 el elemento mayor es 3.
Por lo tanto, el máximo común divisor de 9 y 57 es 3.
Answer:
3
Step-by-step explanation:
9's multiples are 1, 3, and 9. 57's multiples are 1, 3, 19, and 57. The greatest common factor is 3 since that is the highest factor they share.

Find the measures of the complementary angles that satisfy each case.
The measure of the first angle is 40° less than the measure of the second.
Answer: x+(x+40)=90
PLS SHOW UR WORK. IF U ARE ABLE TO, DO A STATEMENT AND REASONING.
Given:
The measure of the first angle is 40° less than the measure of the second.
To find:
The measures of the complementary angles that satisfy the given condition.
Solution:
Let the measure of first angle be x°.
According to the given condition,
First angle = Second angle - 40°
[tex]x^\circ =\text{Second angle}-40^\circ [/tex]
Add 40° on both sides.
[tex](x+40)^\circ =\text{Second angle}[/tex]
We know that, sum of complementary angles is 90°. So,
First angle + Second angle = 90°
[tex]x^\circ +(x+40)^\circ =90^\circ [/tex]
[tex]2x^\circ +40^\circ =90^\circ [/tex]
[tex]2x^\circ =90^\circ -40^\circ [/tex]
[tex]2x^\circ =50^\circ [/tex]
Divide both sides by 2.
[tex]x^\circ =25^\circ [/tex]
So, the measure of first angle is 25°.
[tex](x+40)^\circ =(25+40)^\circ =65^\circ[/tex]
So, the measure of second angle is 65°.

what is the slope of a line perpendicular to the line whose equation is x+y=-1
F(x)=2x^2+16x-7 in vertex form
f(x) = 2 ( x² + 8x ) - 7
= 2 [(x + 4)² - 4²] - 7
= 2 (x + 4)² - 32 - 7
= 2 (x + 4)² - 39
