Answer:
Step-by-step explanation:
42(3.14)=131.9(nearest tenth)
Answer: B
Explaination: hope it helps
Slope intercept form is y=Mx + b the mx is the slope and the b is the intercept you should have to only plug in the equation so I believe it 15= -5yx+b hope this helped !
Answer:
A 4* (7 - 3)
Step-by-step explanation:
Let's do this part by part. First we have "subtract 3 from 7:" this means we are taking 3 out of 7.
7 - 3
Next we have "then multiply by 4." So we need to take the above quantity and multiply the whole thing by 4.
(7-3) x 4
or
4 * (7-3)
The answer is A.
Answer :
x = 53.85
Step by step explanation:
If 78% of x (some numbers) is equal to 42, then we must set this as an equation to find it.
1) Rewriting 78% as a fraction and considering that when we say 78% of some number (x) we mean a product.
78% = 78/100 ➡️ 78/100x = 42
2) Then we can go on :
100 * 78/100x = 42 * 100
78x = 4200
78x/78 = 4200/78 ➡️ x = 53.85
3) Alternatively, simply dividing 42 by 0.78 (78%) would come to the same result :
42/0.78 = 53.85
