Answer:

the answers are d and b

Step-by-step explanation:

d. 19x - 18 = -19x + 18

38x - 18 = 18

38x = 36

x= 36/38= 18/19

b. 19x + 18= -19x + 18

38x + 18 = 18

38x = 0

x =0

The height of a triangle is 4 in. greater than twice its base. The area of the triangle is no more than 168 in.2. Which inequali

netineya [11]

Let

x-------> the length of the base of triangle

y-------> the height of the triangle

we know that

the area of the triangle is equal to

$A=\frac{1}{2}xy$

in this problem we have

$A \leq 168\ in^{2}$

$\frac{1}{2}xy\leq 168$ --------> equation $1$

$y=2x+4$ --------> equation $2$

Substitute equation $2$ in equation $1$

$\frac{1}{2}x[2x+4]\leq 168$

$x^{2}+2x \leq 168$

therefore

<u>the answer is</u>

The inequality that can be used to find the possible lengths, x, of the base of the triangle is $\frac{1}{2}x[2x+4]\leq 168$ or $x^{2}+2x \leq 168$

John is five years older than his sister. the product of their present ages is 150.

liraira [26]

Answer:

john's age= x + 5

his sister's age= x

x + 5 + x = 150

2x + 5 = 150

2x = 150 - 5

2x = 145

x = 145 ÷ 2

x = 72.5

so, 72.5 + 5 = 77.5

john's present age is = 77.5

his sister's present age is = 72.5
