Answer :

Equation :

2y + 3 = 51

Solving :

• 2y + 3 = 51

• 2y = 51 - 3

• 51 - 3 = 48

• 2y = 48

• y = 48 ÷ 2

• 48 ÷ 2 = 24

• so , y = 24

Genrish500 [490]

Answer:

Jamal needs to save $254.17 each month to cover his expenses.

Step-by-step explanation:

We know that there are 12 months in a year, and Jamal already has $1,000 towards college. Jamal still needs to save $3,050 more dollars because: 4,050 - 1,000 = 3,050. Next, we take how much he has yet to pay ($3,050) divided by how many months in 1 year (12), and that gives us 254.17 per month.

Please help I’ll make you the brainiest
Kitty [74]

Answer:

Length of smaller side = 15 inches

Length of bigger side = 36 inches

Length of hypotenuse = 39 inches

Step-by-step explanation:

Given:

Length of smaller side = a

Length of bigger side = (a + 21) inches

Length of hypotenuse = (a + 24) inches

Find:

Length of all side

Computation:

Using Pythagorean theorem

Hypotenuse² = Base² + Perpendicular²

(a+24)² = a² + (a+21)²

a² + 576 + 48a = a² + a² + 441 + 42a

a² - 6a - 135 = 0

(a-15)(a+7)

So

a = 15 inches a = -7 inches

So,

Length of smaller side = a = 15 inches

Length of bigger side = (a + 21) inches = 15 + 21 = 36 inches

Length of hypotenuse = (a + 24) inches = 15 + 24 = 39 inches
