Answer:
18-7=11
Step-by-step explanation:
x-7
x=18
substitute
18-7
=11
area of a triangle=(base x heigth)/2
data:
base=0.5 m
area=12 m²
Therefore:
12 m²=(0.5 m x height)/2
2*12 m²=0.5 m x hegith
24 m²=0.5 m x hegith
hegith=24 m²/0.5 m
heigth=48 m
Answer: heigth=48 m
Answer:
- 72÷8
Step-by-step explanation:
C is the correct answer because each box holds 8 jars of pickles so 72 jars would be divided by 8 to find how many boxes
$13,000 was invested at 6% whereas $7,000 was invested at 10% using simple interest approach
What is simple interest?
Simple interest is determined as the amount invested multiplied by the interest rate and the number of years that investment lasts.
I=PRT
I=interest
P=principal
R=rate of return
T=time
Let X be the amount invested at 6%
I at 6%=6%*X*1
I=0.06X
The amount invested at 10% is 20,000-X
total interest=0.06X+0.10*(20000-X)
total interest=1,480
1480=0.06X+0.10*(20000-X)
1480=0.06X+2000-0.10X
1480-2000=0.06X-0.10X
-520=-0.04X
X=-520/-0.04
X=13,000
13,000 was invested at 6%
amount invested at 10%=20,000-X
amount invested at 10%=20,000-13,000
amount invested at 10%=7,000

Answer: -7/9
Step-by-step explanation: To identify the slope of this line, first notice that this equation is in standard form which is Ax + By = C.
To find the slope, we need to solve for our variable <em>y</em>.
We first need to identify what is happening to our variable <em>y</em>. You can notice that it's being multiplied by 9 and is being added by 7x because 7x is a +7x so we're adding the 7x to the 9y.
So the first thing we do is undo addition and subtraction to our variable.
On the left the -7x's cancel and we are left with 9y. on the right, we do not want to write 45 - 7x because we always want to keep our variable in front of our constant. So I will just write that as 9y = -7x + 45.
Now we can divide everything by 9 in order to get <em>y</em> by itself.
This leaves us with <em>y = -7/9x + 5</em>.
Now our slope is the multiplier or the coefficient of the <em>x</em> term which in this case is -7/9. So the slope is -7/9.
