Lilly babysits for $10 per hour. She works for 5 hours. She uses her money to buy a new sweater that cost $20.
How much money will Lilly have left?

Answer:

Pn=Po(1+r)^n

r=8.7%=8.7/100=0.087

Po=$70

n=1

P1=70(1+0.087)^1

=70(1.087)=76.09

=76

Answer:$76.09

Step-by-step explanation:

100%+8.7%=

 108.7%\,\,108.7\%108.7%

Whole balance before interest = 100%, then add on interest

108.7% of the current balance means 108.7100 of it.\text{108.7\% of the current balance means \(\frac{108.7}{100}\) of it.}108.7% of the current balance means 100108.7​ of it.

"Percent" literally means "out of 100."

108.7100=\frac{108.7}{100}=100108.7​=

 1.087\,\,1.0871.087

To find 108.7% of the current balance, multiply by 1.087:\text{To find 108.7\% of the current balance, multiply by \(1.087\):}To find 108.7% of the current balance, multiply by 1.087:

$70×1.087=\$70\times1.087=$70×1.087=

Answer: B) 40 miles for 5 hours

Divide both values by 5 and we'll simplify that to 8 miles for 1 hour. This is the same as saying 8 miles per hour, or 8 mph.

The ratio 8:1 is read as "8 to 1", meaning the first value is 8 times that of the second value. Note how 40 is 8 times that of 5, ie 40 = 8*5.

Answer:

y+4=-3(x+1)

Step-by-step explanation:

point slope form = y-y1=m(x-x1)

so plug in the numbers

y - -4 = -3 (x - - 1)

if there are two negatives it becomes a positive so your final answer is y + 4 = -3 (x +1)

Hope this helps

Answer:

- 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 7x - 5 ← is in slope- intercept form

with y- intercept c = - 5

The y-intercept of the line y = 7x - 5 is -5.

To find the y-intercept of the line represented by the equation y = 7x - 5, we need to determine the value of y when x is equal to zero. The y-intercept represents the point where the line crosses or intersects the y-axis.

In this case, when we substitute x = 0 into the equation, we get:

y = 7(0) - 5

y = -5

Therefore, the y-intercept of the line y = 7x - 5 is -5. This means that the line intersects the y-axis at the point (0, -5), with the y-coordinate being -5. Graphically, this indicates that the line crosses the y-axis at a height of -5 units.

Answer:

x+y = 1

x = 3, y = -2

Step-by-step explanation:

Given the expressions

x-y = 5

x²-y² = 5

From 2:

x²-y² = 5

(x+y)(x-y) = 5 .... 3

Substitute equation 1 into 3;

(x+y)(5) = 5

Divide both sides by 5

x+y = 5/5

x+y = 1

b) To deduce x and y, we will solve the equation below simultaneously

x-y = 5

x+y = 1

Add both equations

x+x = 5+1

2x = 6

x = 6/2

x= 3

Substitute x = 3 into equation 1

Recall from 1:

x-y = 5

3-y = 5

y = 3-5

y = -2

Hence x = 3, y =-2

The value of the expression in can be estimated by using LCM and algebraic rules and it comes 3.64.

To rewrite the equation 2/3x - 2 = 3/7 without fractions, we need to eliminate the fractions by multiplying both sides of the equation by the least common multiple (LCM) of the denominators.

The denominators in this equation are 3 and 7, and their LCM is 21. So, we will multiply both sides of the equation by 21:

21 x (2/3x - 2) = 21 x (3/7)

Simplifying the left-hand side, we distribute the 21 to both terms:

14x - 42 = 9

Adding 42 to both sides, we get:

14x = 51

Finally, dividing both sides by 14, we get

x = 3.64 (rounded to two decimal places)

Therefore, the equation 2/3x - 2 = 3/7, rewritten without fractions, is 14x - 42 = 9. The solution to the equation is x = 3.64.
