Answer:
a = h/5
Step-by-step explanation:
If you had the equation ...
10 = 5a
and you wanted to find the value of the variable, you would divide by its coefficient:
10/5 = (5a)/5
2 = a
__
Here, we have replaced '10' with 'h'. The same (single) step applies: divide by the coefficient of 'a'.
h = 5a
h/5 = a
To put this in "a = " form, swap the sides of the equal sign:
a = h/5
_____
Literal equations just use different symbols (h instead of 10, here). The operations are the same.

Which expression is equivalent to 1.8(2x + 7) - 15?
a 1.2x
b 3.6x - 2.4
0 3.6x - 8
d 16.2x - 15
Answers
Answer:
Option B. 1.8(2x + 7) – 15 = 3.6x – 2.4
Step-by-step explanation:
1.8(2x + 7) – 15
To know which option is correct, let us simplify the above expression. This can be obtained as follow:
1.8(2x + 7) – 15
Clear bracket
1.8(2x + 7) – 15 = 3.6x + 12.6 – 15
1.8(2x + 7) – 15 = 3.6x – 2.4
Thus,
1.8(2x + 7) – 15 is equivalent to
3.6x – 2.4

Does 1/6, -3, V7, -6/5 or 4.5 come first when the numbers are listed from least to greatest? Explain.
Answers
Answer:
-3
Step-by-step explanation:
Given numbers:
1/6, -3, √7, -6/5, 4.5
The smallest one is chosen between the two negatives as all the rest are greater.
- 3 is smaller than - 6/5= -1.2 as 3 > 1.2So the answer is -3
Greetings from Brasil...
Let's look at each number
1/6 = 1 ÷ 6 = 0.16666....
- 3 = - 3
√7:
√4 < √7 < √9, so
2 < √7 < 3 the result of √7 is between 2 and 3
-6/5 = (- 6) ÷ 5 or 6 ÷ (- 5) = - 1.2
4.5 = 4.5
Writing the numbers in ascending order can tell:
- 3; - 6/5; 1/6; √7 and 4.5or (same values - approximated values):
- 3; - 1.2; 0.2; 2.5 and 4.5

Diego bought some raisins and walnuts to make trail mix. Raisins cost $4 a
pound and walnuts cost $8 a pound. Diego spent $30 on both ingredients.
Write an equation to represent this constraint. Let x be pounds of raisins
and y be pounds of walnuts.
Answers
Answer:
4x + 8y = 30
Step-by-step explanation:
Cost of raisins = $4 per pounds
Cost of walnuts = $8 per pounds
Total spent on both ingredients = $30
Let
Pounds of raisins = x
Pounds of walnuts = y
Diego's equation can be represented by
PxQx + PyQy = 30
Where,
Px = price of raisins
Qx = Quantity of raisins (pounds)
Py = price of walnuts
Qy = Quantity of walnuts (pounds)
PxQx + PyQy = 30
4x + 8y = 30

m<3 = 43 degrees
add 43 degrees and 43 degrees and the answer is 86. and since everything equals 180 degrees, 180 - 86 = 94. since there are 2 side needed to be solved divide 94/2 = 47
so 47 degrees for <2 and 47 degrees for <4
to check my work just add up all the sides
47 degrees for <2, 47 degrees for <4, 43 degrees for <1, 43 degrees for <3
47 + 47+ 43+ 43= 180 degrees

Change -3x+3y=9 into slope intercept form
Answers
To convert to slope-intercept form, we need to get the y by itself.
First add 3x to both sides to get 3y = 3x + 9.
I put the x term first because in slope-intercept form or y = mx + b form,
the x term will always come before the constant term.
Now divide both sides by 3 to get y = x + 3.
Answer:
y = x + 3
Step-by-step explanation:
-3x + 3y = 9
3y = 9 - 3x
