Answer:
41
Step-by-step explanation:
In order to find the measure of angle C we must find the value of x
Remember the measures of the angles in a triangle add up to equal 180
that being said we use this equation to solve for x
180 = (sum of angles) 63 + 2x + 8 + x + 7
now we solve
step 1 combine like terms
63 + 7 + 8 = 78
2x + x = 3x
now we have 180 = 78 + 3x
step 2 subtract 78 from each side
180 - 78 = 102
78 - 78 cancels out
now we have 102 = 3x
step 3 divide each side by 3x
102/3=34
3x/3=x
we're left with x = 34
Now to find the measure of angle C
We plug in the value of x in the expression (x + 7)
so c = 34 + 7
34 + 7 = 41
therefore your answer is 41

Eunice wanted to save up for a mountain bike that costs £250. She baby-sits each week for 6 hours for £2.75 an hour, and does a Saturday job that pays £27.50. She saves 3/4 of her weekly earnings. How many weeks will it take her to save enough to buy the bike?
Answers
Answer:
Approximately 2 weeks
Step-by-step explanation:
Given data
Cost of bike= £250
Assuming she works for 6 days
1.Babysitting
6*2.75=£16.5 per day
for 6 days
=16.5*6
=£99
2. Saturday Job
=£27.50
Total earnings for the week
=£27.50+£99
=£126.5 weekly
Hence it will take her
=250/126.5
=1.97 week
Approximately 2 weeks to save up the amount

Benjamin rode tghe train for 45 minutes. Then it took him another 30 minutes to walk to his friend's house. How many hours did he spend riding and walking to his friend's house?
Answers
Answer:
1.25 hours
Step-by-step explanation:
Benjamin rode tghe train for 45 minutes. Then it took him another 30 minutes to walk to his friend's house. How many hours did he spend riding and walking to his friend's house?
The number of hours he spent riding and walking to his friends house is calculated as:
45 minutes + 30 minutes
= 75 minutes
Converting this to hours
60 minutes = 1 hour
75 minutes = x
Cross Multiply
60 × x = 75 × 1
x = 75/60
x = 1.25 hours

Line N: y = −2x + 6
Which of the following options shows the solution to the system of equations and explains why? Please do it quickly
Group of answer choices
(1, 4), because the point does not lie on any axis
(1, 4), because one of the lines passes through this point
(1, 4), because both lines pass through this point
(1, 4), because the point lies between the two axes
Answers
Answer:
The answer is (1,4) because both lines pass through this point.
Step-by-step explanation:
To find a solution to a system of equations, both lines have to pass through the same point. If both lines intercept at the same point, that means that point is the solution to the system of equations.

Answers
Answer:
y = (x + 1)(x - 0.586) ( x - 3.414)
Step-by-step explanation:
I sure wouldn't recommend doing this by trial and error.
I made a graph of which you can see. Every time this monster touches the x axis and speeds away upward is two equal roots of y. So the square root would be one of each of them.
y = (x + 1)^2 (x - 0.586)^2 (x - 3.414)^2
are the listed roots.
The square root is
y = (x + 1)(x - 0.586) ( x - 3.414)
Do I know that this is right? I don't. But I can tell you this: if you multiply 1^2 * (-0.586)^2 * (- 3.414)^2
you get 4 just as you should. Amazing that we have tools that do that sort of thing.
The first term of an arithmetic sequence is -140 and the 90th term is 483. What is the value of the 55th term?
Answers
Answer: 238
Step-by-step explanation:
The formula to calculate the nth term of an arithmetic progression = a + (n-1)d
Based on the question,
a = -140
90th term = a + 89d = 483
We need to get the value of the common difference
a + 89d = 483
-140 + 89d = 483
89d = 483 + 140
89d = 623
d = 623/89
d = 7
Therefore 55term will be:
= a + (n - 1)d
= a + (55 - 1)d
= a + 54d
= -140 + 54(7)
= -140 + 378
= 238

Step-by-step explanation:
To find the y- intercept let x = 0
From the table for f(x)
When x = 0 → f(x) = - 4
That is the y- intercept = - 4
Given
g(x) = 3 [tex](2)^{x}[/tex]
let x = 0 , then
g(0) = 3 [tex](2)^{0}[/tex] [ [tex]2^{0}[/tex] = 1 ]
= 3 × 1
= 3
That is the y- intercept = 3
Thus the y- intercept of g(x) is greater → B

Answers
Answer:

Step-by-step explanation:
Given 4v-3
evaluate when v = -5
So basically we want to find the value of the expression when the variable (v) equals -5
so
* plug in -5 for v*
4(-5)-3
4*-5=-20
-20-3=-23
So we can conclude that when v = -5 the value of the expression is -23
Answer:
4v-3 = -23Explanation:
given the expression: 4v-3
if v = -5
4v-3 (let's subsitute v)
4v-3 = 4×(-5)-3
4v-3 = -20 - 3
4v-3 = -23
