Mr. Peery has saved $150 to buy an iPhone 12. With his cell phone plan he can buy a new iPhone 12 for $200. If he can only save $10 a week how many weeks will it take for him to get enough money to buy the phone?
Create an equation for the problem here. Don't put any spaces.
How many weeks will it take?
Answer:
Let number of weeks be x
10x = 200-150
x=50/10
x=5
Thus it would take him 5 weeks to buy himself a iPhone12

What is the slope-intercept form of the equation 8x + 7y - 2 - 0?
Answer:
y = -8x/7 + 2/7
Step-by-step explanation:
8x + 7y - 2 = 0
7y = -8x+2
y= (-8x + 2)/7
y = -8x/7 + 2/7
slope = -8/7, intercept = 2/7
Solve the system by substitution.
y = 8x
y = 4x + 8
Answer:
y = 16
x = 2
Step-by-step explanation:
y = 8x
y = 4x + 8
then, by substitution:
8x = 4x + 8
8x - 4x = 8
4x = 8
x = 8/4
x = 2
y = 8x
y = 8*2
y = 16
Check:
y = 4x + 8
y = 4*2 + 8
16 = 8 + 8

The cost of an adult ticket is $7 more than the cost of a child ticket
The total cost of the six tickets is 586
Work out the cost of an adult ticket
Answer:
$102.33
Step-by-step explanation:
586= 4t + 2(t+7)
586= 4t +2t +14= 6t +14
572= 6t
95.33=t
adult ticket = t +7
If triangle DEF is dilated by a scale factor of 1/2 with center of dilation at the origin
(0,0), what is the x-coordinate of E'?
Please help 20 points
Answer:
(4,2)
Step-by-step explanation:
I am not able to see your screen well but these are the points that I saw in the beginning for E. 8,4. Your x value is either left or right and your y value is up and down. I saw 8 units right and 4 u it's up. Now your scale factor is 1/2. Remember if the scale factor is less than one the figure reduces. Our rule for dilations is (x,y) → (kx,ky). The scale factor is represented by K. Since your scale factor is 1/2 we know our triangle will reduce. Let's plug 1/2 in our x and y valued.
So E is (8,4). 8*1/2 is 4 and 4* 1/2 is 2. Are new points are E' (4,2).
Please help.

Find the simple interest paid and the amount paid for the loan.
$4800 at 9.9% for 4 years
Answer:
$1900.80
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 9.9%/100 = 0.099 per year,
then, solving our equation
I = 4800 × 0.099 × 4 = 1900.8
I = $ 1,900.80
The simple interest accumulated
on a principal of $ 4,800.00
at a rate of 9.9% per year
for 4 years is $ 1,900.80.
Which expression is equivalent to
27x^2-72x/9x?
Assume that the denominator does not equal zero.
The expression that is equivalent to 27x² - 72x/9x is 3x - 8
How to determine the equivalent expression?The expression whose equivalence is to be determined is given as
27x^2-72x/9x
The above expression can be properly expressed as follows
27x² - 72x/9x
Introduce the use of brackets
So, we have
(27x² - 72x)/9x
Factor out x from the numerator
This gives
(27x² - 72x)/9x = x(27x - 72)/9x
Cancel out the common factor
(27x² - 72x)/9x = (27x - 72)/9
Factor out 9 from the numerator
This gives
(27x² - 72x)/9x = 9(3x - 8)/9
Cancel out the common factor
(27x² - 72x)/9x = 3x - 8
Hence, the equivalent expression is 3x - 8

(N divided by 10) + 6 = 10. What is the value of N
Answer:
[tex]N=40[/tex]
Step-by-step explanation:
1) Remove parentheses.
[tex]\frac{n}{10} +6=10[/tex]
2) Subtract 6 from both sides.
[tex]\frac{n}{10} = 10-6[/tex]
3) Simplify 10-6 to 4.
[tex]\frac{n}{10} = 4[/tex]
4) Multiply both sides by 10.
[tex]n=4 times 10[/tex]
5) Simplify 4 times 10 to 40.
[tex]x=40[/tex]
Therefor, the answer is x=40.
Answer:
N = 40
n / 10 + 6 = 10
n / 10 - 6 = - 6
n / 10 = 4
n x 10 = 4 x 10
n = 40
Check answer: (40/10) + 6 = 10

You are offered two different sales jobs. The first company offers a straight commission of 8% of the sales. The second company offers a salary of $ 500 per week plus 3% of the sales. How much would you have to sell in a week in order for the straight commission offer to be at least as good
Answer:
You would have to sell 10,000 in a week for the straight commission offer to be at least as good.
Step-by-step explanation:
From the information provided, you can find how much you would have to sell in a week in order for the straight commission offer to be at least as good by establishing an equation in which the amount earned in the first company is equal to the amount earned in the second company:
0.08x=500+0.03x, where x is the amount of sales
Now, you can solve for x:
0.08x-0.03x=500
0.05x=500
x=500/0.05
x=10,000
According to this, the answer is that you would have to sell 10,000 in a week for the straight commission offer to be at least as good.

Responder:
Si el factor de escala de una figura es mayor que uno, la figura es mayor.
Explicación paso a paso:
Hará que la figura sea más grande porque si es menor que uno, la figura será menor. Por ejemplo, si el factor de escala es la mitad de la cifra, será la mitad más pequeña que la cifra original. Y si el factor de escala es 2, la figura será dos veces más grande que la figura original.

sea level is zero so cant be above that and the answer has to be below -100 and the only option is -125
Answer:
A -125

Point A is located at (-2,-2). Plot all of the points 3 units away that have the same y-coordinate as point A.
Answer:
Points are ( 1, -2) , (-5, -2)
Step-by-step explanation:
the given point is A ( -2, -2)
If we fix the y coordinate , then we can change only x coordinate
As we want point 3 unit away
So, add 3 and subtract 3 from x coordinate to find the resultant point
If we add 3 to x coordinate , we get
-2 + 3 = 1
So the point be ( 1, -2)
If we subtract 3 to x coordinate , we get
-2 - 3 = -5
So the point be ( -5, -2)
