Answer:
x = 4
Step-by-step explanation:
Given
4(x + 1) - 9 = 11 ( add 9 to both sides )
4(x + 1) = 20 ( divide both sides by 4 )
x + 1 = 5 ( subtract 1 from both sides )
x = 4
Answer:
Step-by-step explanation:
4x + 4-9=11
4x -5 =11
4x -5+5 =11+5
4x =16
4x divide by 4 is equal to 16 divide by 4
x is equal to 4
Jose has $178.74 in his checking account. He wrote checks for $36.52, $18.92, and $25.93. He also deposited $300.00, $100.00, and $205.16. What is the final balance in Bob’s checking account?
Answer:
$702.53
Step-by-step explanation:
178.74
36,52+18.92+25.93=81.37
178.74-81.37=97.37
300+100+205.16=605.16
605.16+97.37=702.53
The final balance is 702.53 dollars.
If T is the midpoint of SU, what are ST, TU, and SU.
*Question 16*
We have ST=5x, TU=3x+32 and they're equal if T is the midpoint:
5x = 3x + 32
2x = 32
x = 16
ST = 5x = 80
So TU = 80 and SU=160
Answer: Second choice
-5x - 2y = 13
-4x + y = 0
Solve by substation
Answer:
(x,y)=(-1,-4)
Step-by-step explanation:
-4x + y = 0
+4x +4x
y=4x
-5x - 2y = 13
+5x +5x
-2y = 5x+13
-2(4x) = 5x+13
-8x=5x+13
-5x -5x
-13x/-13=13/-13
x=-1
Thus:
y=4x
y=4(-1)
y=-4
7y-9=3y+27 y= please help!
Answer:
Y=9
Step-by-step explanation:
Single out the variable, so subtract 3y from both sides.
7y-9-3y=3y+27-3y
4y-9=27
Then move the value to one side, so add 9 to both sides.
4y-9+9=27+9
4y=36
Then divide 36 by 4
4y/4=36/4
y=9

The ratio of boys to girls in the sixth grade is 2:3
1)If there are 24 boys, how many girls are there?
2)If there are 80 students, how many are girls?
Answer:
3*16=48 girls (further explination below)
Step-by-step explanation:
80/(2+3)=16, so since 3 in the ratio is for girls, there are 3*16=48 girls.

Write the domain and the range of the function as an inequality, using set notations, and using interval notation. Also describe the end behavior of the function or explain why there is no end behavior (19 points and brainliest)
Answer:
Step-by-step explanation:
I think we need to define domain and range first.
Domain is the set of all x values where the function f(x) exists or is defined.
Range is the set of all y values that will result from substituting all x values (the domain) into the function.
So for g(x) = 2x - 2 we can evaluate g(x) at any point, and we will get a real answer for y.
So the range of g(x) = 2x -2 is also all real numbers, because no matter what value of x is, we can always multiply that number by 2 and subtract 2.
The inequality does not affect the domain and range of linear functions at all. Don't confuse domain and range with a solution to an inequality. These two concepts are different. Domain and range mean all possible values of x and y that could be substituted into the inequality. A solution means all possible values that make the inequality statement true.
The domain as an inequality would be -∞ < x < ∞
The range as an inequality would be -∞ < y < ∞
As a set notation:
Domain {x | -∞ < x < ∞}
Range {y | -∞ < x < ∞}
In interval notation:
Domain (-∞ , ∞)
Range (-∞ , ∞)
End behavior:
As x gets larger and larger, g(x) gets larger and larger as well, and as x gets smaller, g(x) gets smaller too.

What is X?
Please help me
Answer:29° because the angle in between x and 105 is 54(alternate angles) in theory angles on a straight line add upto 180° so therefore x+105+54=180 thus x+159=180 as a result the remaining angle (x) would be 180-159=29° therefore x=29°

B is the midpoint of AC
А
B
If:
AB = 62 – 7 and
BC = 5x - 3
Find AC
Answer:
AC = 110Step-by-step explanation:
B being the midpoint of AC means:
AB = BC = 0.5AC
AB = 0.5AC ⇒ AC = 2AB
AC = 2(62 - 7) = 2×55 = 110
Easton paid $68 for his plastic interlocking block set. Colin paid $17 for his plastic interlocking block set. How many more times did Easton pay then Colin
Answer:
4 more times
Step-by-step explanation:
The question says that easton paid 68 dollars for the interlocking set
Colin paid 17 dollars for his own.
We are required to find how many more times easton paid than colin
To do this we divide 68dollars by 17 dollars
68/17
= 4 times
This tells us that compared to colin, easton overpaid for his own set by 4times. Easton paid 4 more times than colin
