Explanation: All 3 angles of a triangle add up to 180, so basically the equation is (3x-5)+(7x+5)+90=180.
Then you add your like terms, so 3x+ 7x=10x and -5+5=0, which cancels out. Now we have 10x+90=180, we subtract the 90 from 180 to see what 10x is equal to and we get 90. So 10x=90. We divide 10 from 90 and we get the value of X, which is 9.

Answer:
(-3, 1)
The solution is the point at which both lines intersect.
This is the solution since both lines would have that point and only that ppoint in this type of problem. IN a graph where 2 lines are parralel, there is no solution as they never intersect . on a graph where the 2 lines overlap there is infinite solutions. FInally in a graph like this there is exactly one solution and it is the intersection of both lines

s Yesterday, two friends went bank to open savings accounts. Reid started by putting $100 in his account, and
he will deposit an additional $40 each week. Akira made no initial deposit, but she will add $50 more each week. In
a few weeks, the friends will have the same account balance. How many weeks will that take?
runt Balance
Answers
Answer:
The two friends will have same account balance in 10 weeks.
Step-by-step explanation:
Given that:
Amount deposited by Reid = $100
Amount deposited each week = $40
Let,
x be the number of weeks.
R(x) = 40x + 100
Amount deposited by Akira each week = $50
A(x) = 50x
For the two friends to have same account balance,
A(x) = R(x)
50x=40x+100
50x-40x=100
10x=100
Dividing both sides by 10
[tex]\frac{10x}{10}=\frac{100}{10}\\x=10[/tex]
Hence,
The two friends will have same account balance in 10 weeks.

The sum of two numbers is 26. Their dif.
ference is 4. Find the smaller number
Answers
x + y = 26
x - y = 4
---
Add to get:
2x = 30
x = 15
---
Solve for "y":
x + y = 26
15 + y = 26
y = 11 (smaller number)
Answer:
The smaller number is 11
Step-by-step explanation:
Let x represent one number and y represent the other.
Since the sum of 2 number is 26, x + y = 26.
The difference of the 2 numbers is 4, so x - y = 4.
x + y = 26
x - y = 4
Solve by combing the two equations:
x + x + y - y = 26 + 4
2x = 30
x = 15
x - y = 4
15 - y = 4
y = 15 - 4 = 11
Since 11 < 15, the smaller number, y , is 11.

Answers
Answer:
yes they are proportional
Answer: It's not
Step-by-step explanation: Proportionality (if that's a word) is basically changing a fraction to a proportion. So 8:14 is basically 4:7, and 29:35 is just that since it can't be simplified. Obviously the two aren't equal, so its not proportional to each other.

How many soultions? -4x-7+10x=-7+6x
A. No solutions
B. Exactly one solution
C. Infinitely many solutions
Answers
Answer:
C. Infinitely many solutions.
Step-by-step explanation:
-4x - 7 + 10x = -7 + 6x
Combine like terms on the left side. Rearrange the right side.
6x - 7 = 6x - 7
Add 7 to both sides.
6x = 6x
Subtract 6x from both sides.
0 = 0
0 = 0 is a true statement.
Both sides are equal, so all real values of x make the equation true.
Answer: C. Infinitely many solutions.

Answer:
x = 14
Step-by-step explanation:
Similar triangles have the property that the measure of its corresponding sides is proportional.
This can be written as:
[tex]\displaystyle \frac{x+1}{27}=\frac{5}{x-5}[/tex]
Cross-multiplying the fractions:
[tex](x+1)(x-5)=27(5)[/tex]
Operating:
[tex]x^2-4x-5=135[/tex]
[tex]x^2-4x-140=0[/tex]
Factoring:
(x-14)(x+10)=0
Solving:
x=14, x=-10
Only positive values can be accepted for x, thus:
x = 14
