for my sister
use the expression 6.3×15÷3±6.8-28.09
to create an expression that includes a
set of parentheses so that the value of
the expression is 46.25

Answer:

Step-by-step explanation:

We first have to cross multiply,

we do 2 times 6 = 12

then 5 times 3 = 15

then we simplify which gets us

4/5 which is the last option so

4/5 is the answer

The question goes Ahmad bought 4 CDs that were each the same price. Including sales tax, he paid a total of $57.60. Each CD had a tax of $1.10. What was the price of each CD before tax?

Price of 4CDs before tax = 57.60 - 4*1.1 = 53.2

Price of each CD before tax = 53.2/4 = $13.3

Answer: 3* (36 - 5x)

Step-by-step explanation:

The total area of the flower garden is equal to the surface of the rectangle that encloses the flower's border and the sitting area minus the area of the sitting area.

Rectangle area

Three flower segments height ----  9  feet

4 flower segments length  ----------- 12 feet

Rectangle area = 12*9 ft^2  = 108 ft^2

Sitting area

Sitting area = 3x*5 = 15x

Area of the flower border (A_flwb)

A_flwb = 108 ft^2 - 15x = 3* (36 - 5x)

Answer:

A: 80 and B: 5.5

Step-by-step explanation:

For A, just multiply 20 and 4 and which you would get 80 miles. And for B, if 1 inch is equal to 20 miles, you can divide 110 and 20 but the answer will be 5.5 rather than 5.

I think this is right but if you can, try and see if it’s correct later.

The person who answered first is correct.

Step-by-step explanation:

Answer:

If you were taught that the first element in the sequence is at n = 0:

-7 - 5n

If you were taught that the first element is at n = 1:

-2 -5n

Step-by-step explanation:

First, find a pattern in the elements of the sequence. At first glace, I notice that each consecutive number is the previous number minus 5.

Thus it can be seen that for each consecutive number in the sequence, 5 is subtracted from negative 2 n times! Therefore, the expression must be:

-2 - 5n

Let's double check the expression! When n = 3, it should equal -17.

-2 - 5(3) = -17

And when n = 5, it should be -27:

-2 - 5(5) = -27.

This is the case if the first element in your sequence is n = 1, if you've been taught that the first element is n = 0, the expression would be:

-7 - 5n

Answer: 76°

Step-by-step explanation:

Parallelograms have parallel sides.

That means AB || DC and AD || BC

We know ∠DAC is equal to 76° and by Alternate Interior Angles, ∠DAC ≅ ∠5.

Answer:

48 people

Step-by-step explanation:

Count all the numbers in the chart

12 + 8 + 10 = 30

First: 12 + 8 = 20

Next: 20 + 10 = 30

Divide 120 by 30 to get 4, which is how many people of a number is chosen

If a number is 12, and the people per number is 4

12 x 4 = 48

[tex]4 \frac{4}{15}[/tex]

Step-by-step explanation:

Given expression:

[tex]5\frac{1}{3} \div 1\frac{1}{4}[/tex]

Rewrite the mixed numbers as improper fractions:

[tex]\implies \dfrac{5 \times 3+1}{3} \div \dfrac{1 \times 4+1}{4}[/tex]

[tex]\implies \dfrac{16}{3} \div \dfrac{5}{4}[/tex]

To divide fractions, flip the second fraction, then multiply:

[tex]\implies \dfrac{16}{3} \times \dfrac{4}{5}[/tex]

[tex]\implies \dfrac{16\times4}{3\times5}[/tex]

[tex]\implies \dfrac{64}{15}[/tex]

Divide the numerator by the denominator:

[tex]\implies 64 \div 15 = 4 \; \rm remainder\;4[/tex]

The mixed number answer is the whole number and the remainder divided by the denominator:

[tex]\implies 4 \frac{4}{15}[/tex]

Answer:

Step-by-step explanation:

Angle A of a triangle is 1/2 the size of angle C. Angle B is 3/4 the size of angle C. If angle C measures 80 degrees, what are the measures of angle A and angle B?

To figure this out, first, divide 80 by 2 to get the measure of angle A.  To get the measure of angle B, multiply 80x3/4

Answer:

C=55

Step-by-step explanation:

80 + 45 + 5x = 180

125 + 5x = 180

-125          -125

5x/5 = 55/5

x = 11

---------------------------------------

C = 5x

C = 5(11)

C = 55

Answer:

2

Step-by-step explanation:

This question tests on the solving for variables in equations.

This question may seem confusing, but it is actually asking to find the value of x.

Given information from the question,

[tex]3x + 5 = 11 \\ 3x = 11 - 5 \\ 3x = 6 \\ x = \frac{6}{3} \\ x = 2[/tex]

Therefore, 2 is the value from the set that satisfy the equation.
