Answer:

C. 70 = 10x

E. 15x = 105

Step-by-step explanation:

x = 7

Using method of elimination;

A. X + 7 = 17

Substituting the value of x;

7 + 7 ≠ 17 (Incorrect option)

B. 7 = 17 - x

Substituting the value of x;

7 ≠ 17 - 7 (Incorrect option)

C. 70 = 10x

Substituting the value of x;

70 = 10 * 7 (Correct option)

D. X/35 = 5

Substituting the value of x;

7 / 35 ≠ 5 (Incorrect option)

E. 15x = 105

Substituting the value of x;

15 * 7 = 105 (Correct option)

Answer:

Step-by-step explanation:

The formula for this, specific to our circle, is

∠RQP = $\frac{1}{2}$ (arc SP - arc RP) and filling in:

∠RQP = $\frac{1}{2}(170-86)$ and

∠RQP = $\frac{1}{2}(84)$ so

∠RQP = 42°

24x^5-8x^4+12x^3-4x^2 / 4x^2

Margaret [11]

Answer:

The detailed process of simplification is :

Step-by-step explanation:

$\frac{24x^{5} - 8x^{4} + 12x^{3} - 4x^{2} }{4x^{2} }$

= $\frac{24x^{5} }{4x^{2} }$ - $\frac{8x^{4} }{4x^{2} }$ + $\frac{12x^{3} }{4x^{2} }$ - $\frac{4x^{2} }{4x^{2} }$ ..........................separate the terms

= 6 $x^{5-2}$ - 2 $x^{4-2}$ + 3 $x^{3-2}$ - 1 ................ subtract the power of x from denominator

= 6 $x^{3}$ - 2 $x^{2}$ + 3 $x$ -1

= 2 $x^{2}$ ( 3 $x$ -1 ) + (3 $x$ -1 )................................... Take (3 $x$ -1 ) common in (6 $x^{3}$ - 2 $x^{2}$ )

= (3 $x$ -1 ) (2 $x^{2}$ +1) .......................................Take (3 $x$ -1 ) common in whole equation

Keep in mind you would need a total of 120 ounces.
A: Corn cereal comes in 12 oz boxes and the person used 5 boxes, thus taking 60 oz away from the total, leaving 60 oz. Next, you’d have to divide 60 oz by 4 (since that’s how many boxes of wheat cereal were used). Resulting in a wheat box being worth 15 ounces!!
B: 12c+ 15w= 120 (c= corn cereal, w= wheat cereal)
C: 5 boxes of corn cereal with 4 boxes of wheat cereal; 0 boxes of corn cereal with 8 boxes of wheat cereal; 10 boxes of corn cereal with 0 boxes of wheat cereal.
