Answer:
<span>a=15</span>
Explanation:
<span>5a−10b=45</span> , when <span>b=3</span>
Substitute the value of b into the equation.
<span>5a−10<span>(3)</span>=45</span>
Solve for a.
<span>5a−10<span>(3)</span>=45</span>
<span>5a−30=45</span>
<span>5a=75</span>
<span>a=<span>15</span></span>

Answer:
for 7 its b and for 8 its C becuase i took this test and got it right
Step-by-step explanation:
The function p(x) = x^3 is a polynomial. Here the “variable”, x, is being raised to some constant power. The function f(x)=3^x is an exponential function (the variable is the exponent).
Exponential functions tend to get very big very quickly, and though they start out smaller than polynomial functions, they will always eventually become bigger. Notice that the two functions meet at x = 2 and x = 4.
Answer:if it is a function than the total number of kids is X so you answer is
Step-by-step explanation:
X=students
T= Textbooks
$60.00 divided X - 60 =Y
V prism = 4 × (5/2) × (3/2) = 15 units^3;
V cube = (1/2)^3 = 1/8 units^3;
15 ÷ (1/8) = 15 × 8 = 120 cubes;
