Hi I’m suppose to write an equation and solve for it. I can’t figure out what I’m doing, it’s a straight angle. Thank you if you figure this out!
Answer:
Equation: 4x+28= 180
x= 38
Step-by-step explanation:
To solve, you should start by trying to find "x". To do this you can use the expression "4x+28= 180"
TO solve 4x+28= 180, first subtract 28 from both sides:
4x= 152
Then divide by 4;
x= 38
Check your work:
M<1= 38+10 -------> 48
M<2= 114+18 -------> 132
132+48= 180

Leila puts an integer into the "In" box of each machine.
She finds that the answer that appears in the "Out" box of Machine A is the same as the
answer that appears in the "Out" box of Machine B.
What was the answer produced by both machines?
Show how you figured it out
The machines represent equivalent expressions.
The output produced by both machines is 372
The equation represented on machine A is:
[tex]\mathbf{y = 2(5x + 3) - 24}[/tex]
The equation represented on machine B is:
[tex]\mathbf{y = 4(2(x + 11) - 7)}[/tex]
Where: x and y represent the inputs and the outputs, respectively
When the outputs are the same, it means:
[tex]\mathbf{y = y}[/tex]
So, we have:
[tex]\mathbf{2(5x + 3) - 24 = 4(2(x + 11) - 7)}[/tex]
Open brackets
[tex]\mathbf{10x + 6 - 24 = 8x + 88 - 28}[/tex]
[tex]\mathbf{10x - 18 = 8x + 60}[/tex]
Collect like terms
[tex]\mathbf{10x - 8x = 18 + 60}[/tex]
[tex]\mathbf{2x = 78 }[/tex]
Divide both sides by 2
[tex]\mathbf{x = 39 }[/tex]
Substitute 39 for x in [tex]\mathbf{y = 2(5x + 3) - 24}[/tex]
[tex]\mathbf{y = 2 \times (5 \times 39 + 3) - 24}[/tex]
[tex]\mathbf{y = 372}[/tex]
Hence, the output produced by both machines is 372

So...
1/2 of 50 is 25.
-kiniwih426
Answer:
$50
Step-by-step explanation:
Solution:
Let the unknown number be x
50% × x = $25
50/100 × x = 25
x = 25×100/50
x = $50
Varification:
50% of $50 is $25
50/100 × 50 = 25
25 = 25

G
Percentage change: 196
This is a percent of increase.
This is a percent of decrease.
Need help with this question?
Answer:
increase
Step-by-step explanation:
the change from 32 miles to 24 is decrease is 8 difference. % change to 196 is an increase.
The percentage change is 25% and it is a percent of increase.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
To find the percentage change from 32 miles to 24 miles, we first need to calculate the absolute change:
Absolute change = Old value - New value
Absolute change = 32 miles - 24miles
Absolute change = 8 miles
Percentage change = (Absolute change / Old value) x 100%
Percentage change = (8 miles / 32 miles) x 100%
Percentage change = 25%
Which means there is a 25% increase from 32 miles to 24 miles.
Therefore, the percentage change is 25% and it is a percent of increase.

1) make q the subject of the formula 4(q+p)=5+7q
2) Make x the subject of the formula y=2a-bx^2
Answer:
1) [tex]q = \frac{4p}{3} -\frac{5}{3}[/tex]
2) [tex]x = \frac{\sqrt{b -y + 2a} }{b}[/tex]
Step-by-step explanation:
1) 4(q + p) = 5 + 7q
Multiply 4(q + p):
4q + 4p = 5 + 7q
4p - 5 = 7q - 4q
4p - 5 = 3q
[tex]\frac{4p}{3} - \frac{5}{3} = \frac{3q}{3}[/tex]
[tex]\frac{4p}{3} - \frac{5}{3} = q[/tex] or [tex]q = \frac{4p}{3} - \frac{5}{3}[/tex]

A train leaves Zurich at 2240 and arrives in Vienna at 07 32 the next day. Work out the time taken.
The answer is 8 hours 32 minutes
But can someone properly explain how
Step-by-step explanation:
Okay so, 22:40 is 10:40pm
07:32 is am
Time goes up to 60 minutes, it would be 52 minutes at the end(20m to get to 11pm + the 32minutes)
Then there would be 8 hours alone (11 to 7 is 8 hours)
So it takes 8 hours and 52 minutes from 10:40pm to 7:32am
answer choices:
52 degrees
128 degrees
38 degrees
138 degrees
Answer:
128°
Step-by-step explanation:
[tex]x + 52 = 180\\180 - 52 = 128\\x = 128[/tex]
