Answer:Answer:

−78+−12=−138

Step-by-step explanation:

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(-7/8, -1/2) = 8

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(−78×11)+(−12×44)=?

Complete the multiplication and the equation becomes

−78+−48=?

The two fractions now have like denominators so you can add the numerators.

Then:

−7+−48=−118

This fraction cannot be reduced.

The fraction

−118

is the same as

−11÷8

Convert to a mixed number using

long division for -11 ÷ 8 = -1R3, so

−118=−138

Therefore:

−78+−12=−138

Solution by Formulas

Apply the fractions formula for addition, to

−78+−12

and solve

(−7×2)+(−1×8)8×2

=−14+−816

=−2216

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(22,16) = 2

−22÷216÷2=−118

Convert to a mixed number using

long division for -11 ÷ 8 = -1R3, so

−118=−138

Therefore:

−78+−12=−138

Answer: -11/8

you need to find the common denominator which is 8 so the equation changes to
-7/8 + (-4/8)

since both are negatives you just add them together and then put your answer as a negative and get
-11/8

which is the answer as an improper fraction

The SHS step team is selling shs spirit t-shirts to raise money. The orange/black shirt sells for $15 and the black/white shirt
IRINA_888 [86]

Answer:

Option A)

15x + 10y \geq 1000

Step-by-step explanation:

We are given the following in the question:

Cost of orange/black shirt = $15

Cost of black/white shirt = $10

Amount of money to be raised is atleast $1000.

Let x be the amount of orange/black shirt and y be the amount of  black/white shirt.

Thus, we can write the inequality:

15x + 10y \geq 1000

That is the total cost of orange/black shirt and black/white shirt should be greater than or equal to $1000.

Thus, the correct answer is

Option A)

15x + 10y \geq 1000

I need help with a math question but apparently everyone is dead today..
Gwar [14]
The answer is D. I’m assuming this is surface area so here’s my explanation:) ok so the area of the triangle is 6 (4x3 divided by 2) and when you add the other triangle that’s 12. Ok so we have 12 so far. Then the area of the bottom rectangle is 24 (3x8). Then the area of the side rectangle is 32 (4x8). THEN the top rectangle’s area is 40 (8x5). When you add the numbers up (12+24+32+40) you get 108! And of course dont forget the cm2. ( centimeters squared ). :) I hope this helps
