Answers
Answer:
yes he will
Step-by-step explanation:
Hence, if his parents giving him $[tex]35[/tex] per week then he can purchase his game system.
What is the simplification?
Simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
Here given that,
Joe has $[tex]180[/tex] in his bank account he wants to buy a new gaming system for $[tex]250[/tex] in two weeks his parents have offered to lend him money if he needs it he gets $[tex]20[/tex] a week for a allowance
So,
His account saving is $[tex]180[/tex].
He wants to purchase a game system which costs $[tex]250[/tex].
His parents giving $[tex]20[/tex] per week. So iin two weeks it is [tex]20(2)=40[/tex]$.
Then , the total savings he had [tex]180+40=220[/tex]$
So he needs [tex]30[/tex]$ more to purchas his game system
If his parents giving him $[tex]35[/tex] per week then in two weeks it would be [tex]35(2)=70[/tex]$.
Then his total savings are
[tex]180+70=250[/tex]$.
Hence, if his parents giving him $[tex]35[/tex] per week then he can purchase his game system.

Find the measure of the missing angles.
Answers
Add the two smallest angles, which are the same, together and you get 140 degrees. The entire circle is 360 degrees. 360-140=220
Then you have two angles left so you divide 220 by 2
220/2=110 so
C= 110
B= 70

Answers
Answer: 41
Step-by-step explanation:
The horizontal line beneath the angle created is always 180 degrees. Because you are given two equations for each angle created, simply write: 180= (3x-3) +(x+19). This gives you 4x+16=180, of which you subtract 16 to 180 which gives you 164. Finally, divide both sides by 4: 4x/4=164/4 and you will get 41. Hopefully I was of aid to you.

m is the midpoint of AB has coordinates (5, -4), if A has coordinates (6, 1). What are the coordinates of B?
Answers
Answer: (4,9)
Step-by-step explanation: We assume a straight line, so y=mx+b.
We can determine slope, m: Change in x is (6-5)=1. Change in y is (1-(-4)) = 5 Slope is (Change in y)/(Change in x) = 5/1, or 5
y=5x+b
Find b for (6,1)
1 = 5*6 + b
b = -29
y = 5x-29
Since A is (6,1) and m is (5,-4) we can calculate y for x=4 (point B)
y = 5(4)-29
y = -9
B is (4,-9)

What is the value of x?
x =
Answers
Answer:
x = 33
Step-by-step explanation:
Note that there are two parallel lines cut by a transversal (given).
The two angles given are corresponding angles, meaning that there measurements will be the same. Set the equation:
124 = 4x - 8
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
~
First, add 8 to both sides of the equation:
124 = 4x - 8
124 (+8) = 4x - 8 (+8)
124 + 8 = 4x
132 = 4x
Next, divide 4 from both sides of the equation:
(132)/4 = (4x)/4
x = 132/4
x = 33
33 is your answer.
