Hello,
Your answers and explanations are below.
6 - 5xy
5 times the product of x and y. The product of x and y means to multiply. That is where we get this: xy. 5 times that product is where we add 5 to it and get this: 5xy.
7 - 4x
We get this because we know he gets $4 an hour. We just do not know how many hours he babysat. The hours is X and we multiply that by 4.
8 - 5.5
Take 8.3 and subtract 2.8 to find x. Once we do that we get 5.5, and that is X.
9 - We can't see the problem. It's cut off
Good Luck,
- I.A. -
3 eggs for brownies, 2 eggs for cookies.
Because the total count went up 2 for one more batch of cookies, you know that 1C(ookies) = 2 eggs
3C = 6 eggs
15 - 6 = 9 eggs
3B(rownies) = 9 eggs
1B = 3 eggs
The answer is 30 feet per hour
plz thank me, it motivates me to answer more of your questions :)
Answer:
The measure of the largest angle in the kite is 128 degrees
Step-by-step explanation:
we know that
The sum of the interior angles in any quadrilateral must be equal to 360 degrees
A kite is a quadrilateral
Let
A,B,C and D the measure of the interior angles
so
we have that
substitute
----> equation A
Remember that
one is four times larger than the other
so
----> equation B
substitute equation B in equation A
solve for D
Find the measure of angle C
therefore
The measure of the largest angle in the kite is 128 degrees
Answer:
Numbers of students at a primary school before= 240
Number of increased students =42
Again,
Increased number of students in percent(%)= 42/240×100%= 17.5%
Therefore 17.5% students are increased this year.
