Answer:
4 meters
Step-by-step explanation:
Area is length x width
28=7n where n is the unknown width
Solve for n and u get 4
Well, following the order of PEMDAS, I got choice B. 52
For instance, when you plug in 5 for x, you get F(5)=2(5)^2+2.
Moreover, following PEMDAS, you're supposed to solve what's inside the parenthesis, but since there is no operation going on inside the parenthesis, then you simple move on to the exponent.
In this case, you square the number 5, which gives you F(5)=2(25)+2
After that, you Multiply (letter M in PEMDAS). This results in F(5)=50+2.
Finally, you add them, which results in F=52.
By the way, I noticed a mistake in your work. When multiplying 2 by 5, the answer is 10, not 20.
Anyway, hope this helped! :-)
Answer:
As there is Bracket lats solve it first but as there is '-' sign before the bracket sign in the bracket will change. so we will have,
'800+900×25-65(89-5)-12÷67-7'
Solving the bracket gives us:
'800+900×25-65(84)-12÷67-7'
Now avoiding the Bracket:
'800+900×25-5460-12÷67-7'
Now first we have to do MUltiplication, so we will get,
'800+22500-5460-12÷67-7'
Now let's do the division, so we will get,
'800+22500-5460-0.17-7'
Now lets do the additions and subtractions we will get,
<h2><u>17,832.83</u></h2>
Answer:
m = 15
Step-by-step explanation:
10m = 10 - 5(m-7)
multiply -5 into the parenthesis
10m = 10 - 5m + 35
add like terms
10m = -5m + 45
add five 5 to both sides
15m = 45
divide by 15 on both sides to isolate m
m = 15
Answer:
Amount of shampoo in a bottle = 30 \frac{1}{2} 30
2
1
ounces
Amount of shampoo Nico uses in one bathe for his dog = 1 \frac{1}{4} 1
4
1
Since 3 ounces of shampoo is spilled out, the amount of shampoo left in the bottle will be = 27 \frac{1}{2} 27
2
1
If Nico can Bathe his dog x times using this bottle, the value of x can be written as:
x= \frac{27 \frac{1}{2} }{ 1\frac{1}{4} } x=
1
4
1
27
2
1
Using this equation we can find the number of times Nico can use the shampoo to Bathe . The value of x comes out to be 22.
Thus, Nico can Bathe his dog 22 times using the bottle
