Answer:

a = -4

Step-by-step explanation:

To solve for 'a', isolate 'a'.

a - 15 = 4a - 3

Subtract '4a' from both sides,

a - 4a -15 = -3

Combine like terms,

-3a - 15 = -3

Add 15 to both sides,

-3a = -3 + 15

-3a = 12

Divide both sides by (-3),

a = 12 ÷ (-3)

$\sf \boxed{\bf a = (-4)}$

Mitchell bought some pinwheels for a dollar and paid in dimes.how many dimes did she use explain

chubhunter [2.5K]

Well, if the pinwheels cost $1 each, then 10 dimes is what it would take to pay for them. 10 dimes = 1 dollar, because a dime has a value of 10 cents and 10 times 10 = 100, and there is 100 cents in a dollar.

Write a linear equation that passes through the point (2,-9) and has a slope of -5

Anna [14]

Answer:

y = -5x + 1

Step-by-step explanation:

Given:

The slope m = -5 and point (2, -9)

Use point slope form:

y - y₁ = m(x - x₁), where (x₁, y₁) is the given point

So the equation is:

y - (-9) = -5(x - 2)
y + 9 = -5x + 10
y = -5x + 1
