Answer:
5x + 70 = 320
Step-by-step explanation:
We know that Carmine paid an electrician a certain amount per hour, we also know that they worked for 5 hours. Therefore we have 5x.
He also got paid 70 for parts, meaning an extra $70
And we know that we have the total charge and that the main point of this question is to determine how much the electrician was paid per hour.
Therefore :
5x + 70 = 320
Your teacher is giving you a test tomorrow with 2- and 4-point questions for a total of 100 points. The number of 4 points questions is one-third the number of 2-point questions. How many 2- and 4-point questions are on the test?
Answer:
25 4-point questions and 75 2-point questions
Step-by-step explanation:
Let x = no. of 4-point questions
Then 3x = no. of 2-point questions
So, x + 3x = 100
4x = 100
x = 25 = no. of 4-point questions
and 3x = 3(25) = 75 = no. of 2-point questions
A square has a perimeter of 62 inches what is the length of each side
Answer:
15.5 in
Step-by-step explanation:
perimeter = all way round
62 / 4 (sides) = 15.5
42 = y + 15 whats y? y == __
Solution
[tex]y=27[/tex]
Step-by-step explanation:
Subtract [tex]15[/tex] from both sides of the equation:
[tex]42=y+15[/tex]
[tex]42[/tex][tex]-15=y+15[/tex][tex]-15[/tex]
Simplify:
Subtract the numbers:[tex]42-15=y+15-15[/tex]
[tex]27=y+15-15[/tex]
Subtract the numbers:[tex]27=y+15[/tex][tex]-15[/tex]
[tex]27=y[/tex]
Move the variable to the left:[tex]27=y[/tex]
[tex]y=27[/tex]
[tex]y=27[/tex]

the cost of 1 metre of plastic sheet ₹25 1/2. find the cost of 3 1/17 (ans should be ₹78)
Answer:
78
Step-by-step explanation:
1 metre of plastic sheet= 25 1/2
3 1/17 plastic sheet = x
Cross multiply
x = 3 1/17 × 25 1/2
x = 52/17 × 51/2
x = 2652/34
x = 78
Hence the price of 3 1/17 metre of plastic is ¥78
What is the answer !?

Converting from vertex to standard form
[tex]y = (x + 1) {}^{2} - 3[/tex]
[tex]y = (x - 2) {}^{2} + 3[/tex]
Answer:
Step-by-step explanation:
y = (x+1)² - 3
= (x²+2x+1)-3
= x²+2x-2
:::::
y = (x-2)² + 3
= (x²-4x+4) + 3
= x²-4x+7

Find the slope of the line that passes through (2, 12) and (6, 7).
Answer:
m=[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Gladly!
To find the slope, we need to find the change between point a and point b
With the difference between x1 and x2 being 4, and the difference between y1 and y2 being 1, we get a fraction that looks like this,
[tex]\frac{1}{4}[/tex]
This right here is the slope of the line. Hope this helps!
What is the radius of a circle whose area is equal to the sum of the areas of two circles whose radii are 20cm & 21cm?
Answer:
29
Step-by-step explanation:
20^2 times 3.14= 1256
21^2 times 3.14= 1384.74
the sum of those two is 2640.74
the square root of that is 29
The radius of the circle is 29 cm.
We have the circle whose area is equal to the sum of the areas of two circles whose radii are 20cm & 21cm.
We have to find the radius of the circle.
Suppose you have to find the radius of a circle whose area is equal to the sum of the areas of two circles whose radii are r and R. How will you approach it?Let the radius of the circle be x.
We know that the area of the circle is [tex]\pi r^{2}[/tex]. Then -
[tex]\pi x^{2} =\pi r^{2} +\pi R^{2} \\x=\sqrt{r^{2} + R^{2}} \\[/tex]
Now, in the question given to us -
r = 20cm and R = 21cm and 'x' denotes the radius of the circle we have to find.
Substituting the values in the above formula, we get -
x = [tex]\sqrt{400+441}[/tex]
x =29 cm
Hence, the radius of the circle is 29 cm.

Answer:
Part b.
Step-by-step explanation:
Ok, so I think what you can do for part b. is pretty simple. You know that $820 is for 4 weeks of work. 820/4 = 205. So he gets $205 per week. If 820 = 100%, then 205*3 = 75%. So the answer would be he will recieve 75% of his usual pay, and that will be $615.
Missy is getting married and addressing invitations. She has at least 140 envelopes and has addressed 26 of them. Write an inequality that describes how many more invitations must be addressed.
If She has at least 140 envelopes, the required inequality will be x + 26 ≥ 140
Inequality expressionsGiven the following information
Total number of envelopes = 140Number of envelopes that have been addressed = 26 envelopes
Number of envelopes not addressed = 140 - Number of envelopes addressed
x = 140 - 26140 = x + 26If She has at least 140 envelopes, the required inequality will be x + 26 ≥ 140
