(2x + 1) + (7x - 10) = 90. [WXY is a right angle]
9x - 9 = 90
9x = 99
x = 11
WXZ = 2x + 1 = 2 x 11 + 1 = 23 degrees

4x-9=7x+12(if there is no solution,type in ''no solution'') x= Answer
kari74 [83]

Answer:

x = -7

Step-by-step explanation:

4x-9 = 7x+12

Add 9 to both sides

4x = 7x + 21

Subtract 7x from both sides to further isolate the variable

-3x = 21

Divide both sides by -3

x = -7

Plug the value in to check your work:

4(-7) - 9  ?  7(-7) +12

-28 - 9   ?  -49 + 12

-37   ?   -37

-37 = -37

III. Let g(x) = 4x + 1 represent the conversion from spots to stars. Let h(x) = x2 - 2 represent the conversion from stars to as
svlad2 [7]
G ( x ) = 4 x + 1 ( spots → stars )
h ( x ) = x² - 2 ( stars → asteroids )
Composite function:
h ( g ( x ) ) = ( 4 x + 1 )² - 2 = 
= 16 x² + 8 x + 1 - 2 = 
= 16 x² + 8 x - 1 ( spots → asteroids )

Ms. johnson owns a spice shop. she combines 5 pounds of dried rose hips and 1 pound of five-spice powder to make a new seasoning
Burka [1]

Given the 6 pound weight of the new seasoning having ingredients that cost $8, and $11, the amount she should charge for 1 ounce is $0.53125

<h3>Which method can be used to calculate the price of the new seasoning?</h3>

The ingredients in the new seasoning are;

5 pounds of dried rose hips + 1 pounds of five-spice powder

Cost of the ingredients are;

1 pound of dried rose hips = $8

1 pound of five-spice powder = $11

The cost of combined spice, <em>C</em>, is therefore;

C = $8 × 5 + $11 × 1 = $51

The weight of the new combined seasoning = (5 + 1) pounds = 6 pounds

Cost of 1 pound of the new seasoning is therefore;

1 \: lb =  \frac{51}{6}  = 8.5

  • 1 lb of the new seasoning = $8.5

  • 1 lb = 16 ounces

Therefore;

1 \: ounce =  \frac{8.5}{16}  = \mathbf{0.53125}

  • The amount she should charge for 1 ounce is $0.53125
