Answer:

B - 4

Step-by-step explanation:

Okay let's write this out. 3z+a=10, where Zoey and Ayden are z and a respectively. a=2z

We can further simplify by substtitition.

3z+2z=10

5z=10

3(2) + a = 10

6+a=10

a=4

Please brainliest.

Answer:

$\frac{8}{3}$

Step-by-step explanation:

Given

$\frac{7}{3}$ + 3( $\frac{2}{3}$ - $\frac{1}{3}$ )²

= $\frac{7}{3}$ + 3 ( $\frac{1}{3}$ )²

= $\frac{7}{3}$ + 3 × $\frac{1}{9}$

= $\frac{7}{3}$ + $\frac{1}{3}$

= $\frac{8}{3}$

Can someone please professionally explain the math equations below. (Not just answer the question)

Rus_ich [418]

Step-by-step explanation:

We will solve this system of equations using two methods: elimination and substitution.

Method 1: Elimination

2x - y = -8. #1

-5x + y = 26. #2

Note that by adding these two equations, the y-variable is eliminated (thus the name) and you're only left with an equation with one variable. So upon adding, we get

-3x = 18 or x = -6

Using this value for x, put this back in either one of the equations. Let's use the 2nd one.

-5(-6) + y = 26

--> 30 + y = 26

Moving 30 to the right side, we get y = -4.

Method 2: Substitution

This is done by isolating one variable to the left side in one equation and then using it on the other equation. Let's take equation #2 and put the y-variable on the left side and you should get

y = 5x + 26

Now use this equation and plug it into the y in equation #1:

2x - (5x + 26) = -8

--> 2x - 5x - 26 = -8

--> -3x = 26 - 8 = 18 or x = -6.

Use this value for x into either one of the equations. Let's use equation #1 this time.

2(-6) - y = -8

--> -12 + 8 = y or y = -4.

Notice that using either method will give you the same result, as one might expect.

What is the solution to the inequality 15y-9<36

artcher [175]

Answer:

$\boxed{y$

Step-by-step explanation:

15y - 9 < 36 add 9 to both sides

15y < 45 divide both sides by 15

y < 3

Area of trapezoid

Given a trapezoid shape whose parallel sides measure b1 and b2 and whose height (perpendicular to the base) is h, then the area of the trapezoid is given by

$\displaystyle A=\frac{b_1+b_2}{2}\cdot h$
