Answer 1

Answer: (12 + x)/3 = 5

Multiply each side by 3 :

12 + x = 15

Subtract 12 from each side:

x = 3
=================================

x/3 - 5 = 3

Multiply each side by 3 :

x - 15 = 9

Add 15 to each side:

x = 24

–3(t − 17) = 6 whats the answer

Answers

Answer:

t = 15

–3(t − 17) = 6

Step-by-step explanation:

1. Distribute the –3 to the terms inside the parentheses:

–3 * t + 3 * 17 = 6

2. Simplify:

–3t + 51 = 6

3. Next, we want to isolate the variable t by getting rid of the constant term. To do this, we can subtract 51 from both sides of the equation:

–3t + 51 - 51 = 6 - 51

This simplifies to:

–3t = -45

4. Now, to solve for t, we need to isolate the variable. Since –3t means –3 times t, we can divide both sides of the equation by –3:

–3t / –3 = -45 / –3

This simplifies to:

t = 15

So, the solution to the equation –3(t − 17) = 6 is t = 15.

A landscaper is designing a flower garden in the shape of a trapezoid. She wants the shorter base to be 3 yards greater than the height, and the longer base to be 7 yards greater than the height. the total area of the flower garden is 150 square yards. what will the length of each base be

Answers

18 yards and 22 yards are the length of trapezoid.

What is Trapezoid?

Trapezoids are quadrilaterals that have two parallel sides and two non-parallel sides

Given,

shorter base to be 3 yards greater than the height

b₁=h+3

longer base to be 7 yards greater than the height.

b₂=h+7

Area of trapezoid=1/2(b₁+b₂)h

150=1/2(h+3+h+7)h

150=(2h+10)h/2

150=2h²+10h/2

150=2h²+5h

h²+5h-150=0

h²+15h-10h-150=0

h(h+15)-10(h+15)=0

(h-10)(h+15)=0

h=10 or h-15

h value should be positive.

So b₁=h+3=15+3=18

b₂=h+7=15+7=22

Hence the bases be 18 yards and 22 yards.

From your information
Let shorter base = h +3 and longer base = h + 7 where h is the height.
Formula for area of a trapezoid is $A = (1)/(2) (b_1 +b_2)h$
Substituting into the formula we get the following equation.
$150= (1)/(2)(h+3+h+7)h$
$150 = (1)/(2) (2h+10)h$
$150=h^2+5h$
This is a quadratic equation which I will solve by factoring.
$h^2+5h-150 =0$
$(h-10)(h+15)=0$
$h-10= 0 ..... h=10$ this is a useable answer (it's positive and length must be nonnegative)
$h+15=0 .... h=-15$ can't use this answer
so shorter base = 10 + 3 = 13 yards and longer base = 10 + 7 = 17 yards
