The answer is 11/8 but if u have to simplify to mixed fraction it would be 1 3/8. In decimal form its 1.375.

7 - 5 * 8 + 5 over 8
7 - 40 + 5 over 8
7 - 45/8
7 * 8/8 - 45/8
56/8 - 45/8
56 - 45 over 8
11/8
1 3/8

<h3>Answer :</h3>

$\sf \dashrightarrow \dfrac{22}{7} \div \dfrac{22}{7}$

$\sf \dashrightarrow \dfrac{22}{7} \times \dfrac{7}{22}$

$\sf \dashrightarrow \dfrac{\cancel{22}}{\cancel{7}} \times \dfrac{\cancel{7}}{\cancel{22}}$

$\sf \dashrightarrow 1 \times 1$

$\sf \dashrightarrow 1$

<h3>Hence, answer is 1.</h3>

Simplify : 5y-2y+4=10

Mnenie [13.5K]

Answer:

See below.

Step-by-step explanation:

5y - 2y + 4 = 10

5y - 2y = 6

3y = 6

y = 2

Check:

5y - 2y + 4 = 10

5(2) - 2(2) + 4 = 10

10 - 4 + 4 = 10

6 + 4 = 10

10 = 10

The value of y = 2

Answer:

a) The equation (10s + 8w) represents the calories Bridget ate on Monday and the equation (20s + w) represents the calories she ate the next day.

b) The number of calories in each strawberry is 4 and the number of calories in each vanilla wafer cookie is 19. The solution is s= 4 and w = 19.

Step-by-step explanation:

For part A, Bridget ate 10 strawberries and 8 vanilla wafer cookies on Monday. Since the the number of calories in a strawberry is s and the number of calories in a vanilla wafer cookie is w , the number of calories Bridget ate on Monday is 10s + 8w. The next day, Bridget ate 20 strawberries and 1 vanilla wafer cookie. Hence, the number of calories Bridget ate on the next day is 20s + w.

For part B,

we will create two different simultaneous equations.

Equation 1: 10s + 8w = 192

Equation 2: 20s + w = 99

We need to find one of the terms first to solve the other term. For this case, I will solve for w first.

Multiply the first equation by 2.

Equation 3: 20s + 16w = 192*2 = 384.

Now, subtract equation 2 from this new equation.

Equation 4:

(20s + 16w) - (20s + w) = 384 - 99

20s + 16w - 20s - w = 285

15w = 285

This leaves only w left and we can solve w.

w = 285 / 15 = 19

Now, we can solve for s using equation 2.

20s + 19 = 99

20s = 99-19 = 80

Hence,

s = 80/20 = 4
