The sum of 4 twelve and 3 twelves

Answers

Answer 1

Answer: 4+3 = 7 x 12 = 84

Answer : 84

Answer 2

Answer: I think what the question is asking for is this:
4(12) + 3(12)=
That would be 4 twelves plus 3 twelves

Which would be
48 + 36 = 84

Solve each proportion
5/t = t/45

Answers

$45t\cdot \frac { 5 }{ t } =\frac { t }{ 45 } \cdot 45t\n \n 225={ t }^( 2 )\n \n t=\pm \sqrt { 225 } \n \n t=\pm 15$

t = 15 or -15 because you solve proportions by cross multiplying. if you write it out in the following way:

5 t
__= __
t 45

Then, cross multiplying involves multiplying the numerator( number at the top) of one of the fractions with the denominator (number at the bottom) of the other, and setting the two results equal to each other. You get t * t = 5 * 45 and end up with t^2 = 225 or t = (15 or -15)

Please help solve, Really need help can't fail.In the figure above, ABC is similar to XYZ. If the length of side AB is 15 units, the length of side BC is 40 units, and the length of side YZ is 8 units, what is the length of side XY?

A.5 units
B.3 units
C.4 units
D.1 units

Answers

Well, we know that if two polygons are similar, then their sides are proportional. Therefore, side AB is similar to side XY and side BC is similar to side YZ. This means that AB / XY = BC / YZ. From here, plug in values: 15 / XY = 40 / 8. This can be simplified to 15 / XY = 5. Multiply both sides by XY to get it out of the denominator: 15 = 5XY and then divide each side by 5. 3 = XY. This means that the answer is B, or 3 units. To check the answer, put it back into the original equation and make sure it works out.

Tina buys 3 7/8 yards of material at the fabric store. She uses it to make a skirt. Afterward, she has 1 3/8 yards of the fabric leftover. How many yards of material did Tina use?

Answers

The amount of fabric Tina used after she has a leftover of 1 3/8 yards is 2 1/2 yards.

What is a fraction?

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, Tina buys 3 7/8 yards of material at the fabric store, and after she uses it to make it a skirt she has 1 3/8 yards of the fabric leftover.

Therefore the amount of fabric she used is the difference between the total fabric and the leftover which is,

= 3 7/8 - 1 3/8.

= 31/8 - 11/8.

= 20/8.

= 2 4/8.

= 2 1/2 yards.

Jen measured the growth of a sunflower in one week it grew 2 and 1 half inin week two it grew 2 and 3 fourth in
on week 3 it grew 3 and 1 fourth in how much did it grow in the 3 week s
try to explain please

Answers

The totalgrowth of the sunflower over the 3 weeks is 7(1/2) inches.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the liketerms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To find out how much the sunflower grew in the 3 weeks, we need to add up the growth it had each week.

Now,

Firstweek:

The sunflower grew 2 and 1 half inches.

This means,

2(1/2)

Secondweek:

It grew 2 and 3 fourth inches.

2(3/4)

Third week:

It grew 3 and 1-fourth inches:

3(1/4)

To find the totalgrowth over the 3 weeks, we need to add these three mixed numbers together.

= 2(1/2) + 2(3/4) + 3(1/4)

= 7(1/2)

Thus,

The totalgrowth of the sunflower over the 3 weeks is 7(1/2) inches.

so you basically add the amount it grew each week. So week one is 2 and 1/2, week two is 2 and 3/4 and week three is 3 and 1/4. to make things simpler, add week two and three which gets you 6inches, then add week one, to get 8 and a half inches.
