7 0

Answer:

28 strokes

Step-by-step explanation:

The computation is shown below:

It is given that the 42 strokes are required to fill up the 3 by 5th

So for completing the line, the number of additional strokes required is

But before the total strokes required is

= 42 × 5 ÷ 3

= 70

This represent the total

so, the additional strokes is

= 70 - 42

= 28 strokes

What is the solution to the equation One-fourth x + 2 = negative StartFraction 5 Over 8 EndFraction x minus 5? X = negative 8 x
Ede4ka [16]

Answer:

(A)x= -8

Step-by-step explanation:

One-fourth x + 2 = \frac{1}{4}x+2

\frac{1}{4}x+2=-\frac{5}{8}x-5

Next, we Expand the Left hand Side by multiplying each term in the bracket by 1/4

\frac{1}{4}x+\frac{2}{4}=-\frac{5}{8}x-5

Bringing terms with x to the left Hand Side i.e. collecting like terms

\frac{1}{4}x+\frac{5}{8}x=-5-2\\\\(\frac{1}{4}+\frac{5}{8})x=-7\\\\\frac{7}{8}x=-7

On Cross multiplying

7x = -7 X 8

x=-\dfrac{7*8}{7}\\

x=-8

Holly wants to save money for an emergency. Holly invests 1,500 in an account that pays an interest rate of 6.75%. How many year
lina2011 [118]
The formula is
A=p (1+r)^t
A future value 7300
P present value 1500
R interest rate 0.0675
T time?
7300=1500 (1+0.0675)^t
Solve for t
Divide both sides by 1500
7300/1500=1.0675^t
Take the log for both sides
Log (7300/1500)=t×log (1.0675)
Divide both sides by log (1.0675)
T=log(7,300÷1,500)÷log(1.0675)
T=24.2 years round your answer to get 24 years

Hope it helps!
