To solve for x
bx=-7
divide b on both sides
x=-7/b

to solve for b
bx=-7
divide x on both sides
b=-7/x

2 servings because one serving is 4%, so you would need would need to double that, or multiply it by two.

Divide 5 1/2, or 11/2 by 3/4. You can do that by multiplying 11/2 and 4/3 to get 44/6. Simplify and you get 22/3, which is about 7.33 or 7 1/3. If he can only paint whole dog houses, the answer is 7.

Answer:

$x = 9$

Step-by-step explanation:

Given

$\angle S = 45$

$\angle U = 4x - 1$ --- (not clear but that is what I'm able to read)

$\angle Q = 100$

Required

Find x

From the attachment, the corresponding angles of both triangles are equal:

This implies that:

$\angle P = \angle S = 45$

$\angle U = \angle R = 4x - 1$

$\angle Q = \angle T = 100$

Apply angle sums property

$\angle S +\angle T +\angle U =180$

This becomes

$45 + 4x - 1 +100 = 180$

Collect like terms

$4x= 180-45-100+1$

$4x= 36$

$x = 9$
