2(x-3) +9=3(x+1) + x

Mathematics
1 answer:
Licemer1 [7]3 years ago
5 0

Answer:

x = 0

Step-by-step explanation:

2(x - 3) + 9 = 3(x + 1) + x

2x - 6 + 9 = 3x + 3 + x

2x + 3 = 4x + 3

2x - 4x = 3 - 3

-2x = 0

2x = 0

x = 0/2

x = 0

If y - 18 = 14, then what is the value of 3(y + 5) ?
shtirl [24]

Answer: y = 980.333

Step-by-step explanation:

y-18=14

add 18 to each side

y = 32

Substitute 32 for y in 3(y+5)

3(32 + 5)

3(37)

111

So 3(y+5) = 111

Find the value of the variable y:

y-18=14 Add 18 on both sides:

y = 32

= 3y+15

_____________________

3y+15 = 2,956

3y+15 = 2956

3y = 2941

y = 980.333

A rectangle and a triangle have the same area, 72 . The height of the triangle is also the same as the width of the rectangle. T
emmasim [6.3K]

Answer:

Part 1) The height of triangle is h=8\ in

Part 2) The width of rectangle is W=8\ in

Step-by-step explanation:

step 1

Find the dimensions of triangle

The area of triangle is equal to

A=\frac{1}{2}bh

we have

b=18\ in

A=72\ in^{2}

substitute and solve for h

72=\frac{1}{2}(18)h

144=(18)h

h=144/18=8\ in

step 2

Find the missing dimension of rectangle

we have that

The height of the triangle is the same as the width of the rectangle

therefore

W=h=8\ in
