Answer:

Step-by-step explanation:

Set up the following ratio which applies to all angle bisectors and the side opposite.

8 / (x + 4) = 12 / (2x + 1) Cross multiply

8 * (2x + 1) = 12 * (x + 4)

16x + 8 = 12x + 48 Subtract 8 from both sides

16x + 8 -8 = 12x + 48-8

16x = 12x + 40 Subtract 12x from both sides

16x - 12x = 40

4x = 40 Divide by 4

4x/4 = 40/4

x = 10

At a fundraiser breakfast, the bill for three glasses of orange juice and five pancake specials is $7.60, whereas the bill for o

JulsSmile [24]

1) 3j + 5p = 7.60 and 1j + 2p = 2.90

2) Solving for j and p
j = 2.90 - 2p

3(2.90 - 2p) + 5p = 7.60
8.7 - 6p + 5p = 7.60
8.7 - p = 7.60
-p = -1.1
p = 1.1

1j + 2(1.1) = 2.9
j + 2.2 = 2.9
j = .7

3) The values of p and q:
p = $1.1 per pancake, j = .70 cents per glass

A section of ground measures 1.5 cubic meters and contains 0.78 gram of gold. What is the amount of gold per cubic meter? Enter

Marta_Voda [28]

To find the gold per cubic meter you have to divide the amount of gold by the size of the area. So you would do .78/1.5 which would give you .52g/m3

Solve for x: three fourths times x plus five fourths equals four times x

Nostrana [21]

Answer:

x equals five thirteenths

Step-by-step explanation:

To solve this, we will follow the steps below;

$\frac{3}{4}$ × x + $\frac{5}{4}$ = 4 × x

$\frac{3x}{4}$ + $\frac{5}{4}$ = 4x

$\frac{3x + 5}{4}$ = 4x

Multiply both-side of the equation by 4

$\frac{3x + 5}{4}$ × 4= 4x × 4

On the left-hand side of the equation 4 will cancel-out 4, thus the equation becomes;

3x + 5 = 16x

subtract 3x from both-side of the equation

16x - 3x = 5

13x = 5

Divide both-side of the equation by 13

$\frac{13x}{13}$ = $\frac{5}{13}$

(On the left-hand side of the equation 13 at the numerator will cancel-out 13 at the denominator while on the right-hand side of the equation 5 will be divided by 13)

x = $\frac{5}{13}$

x equals five thirteenths
