Answer:
x = 4
Step-by-step explanation:
The steps we need to take:
1. Simplify left side.
2. Separate the variable and its coefficient from constants
3. Divide both sides by the coefficient to find "x
1) Simplify left side.
5(3x - 4) + 12 = 52
15x - 20 + 12 = 52
15x - 8 = 52
2) Separate the variable and its coefficient from constants by adding 8 to both sides.
15x - 8 + 8 = 52 + 8
15x = 60
3) Divide both sides by the coefficient to find x. (the coefficient is the number that comes before the variable)
15x / 15 = 60 / 15
x = 4

Solve the following systems of equation: y = 6x 4x + y = 7
Answer:
y=21/5, x=7/10
Step-by-step explanation:
Substitute y=6x
4x=6x=7
Simplify 4x+6x
10x=7
isolate x for 10x=7:
10x=7
Divide both sides by 10:
10x/10=7/10
Simplify:
x=7/10
For y=6x substitute x=7/10
y=6*7/10
Convert element to fraction:
6/1*7/10
Cross- cancel common factor:2
3/1*7/5
Multiply fractions:
3*7/1*5
Multiply the numbers:3*7=21
=21/5
y=21/5
The solutions to the systems of equations are:
y=21/5,x=7/10

Answer: Hi i hope your doing good well the answer is 55
Step-by-step explanation: Angles one and two are complementary. So we know the sum of their measures is 90 degrees. So, to find the measure of angle two, subtract the measure of angle one from 90 degrees. We substitute in the given value of the measure of angle one, which is 35 degrees. Subtracting, we find that the measure of angle two equals 55 degrees.

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
We have,
Mary earns $247.25 for gardening.

Answer:
45.5625
Step-by-step explanation:
The pattern seems to be x + (x/2) = y where x is the previous number and y is the next number.
4 + (4/2) = 6
6 + (6/2) = 9
therefore we continue the pattern. In doing so we get:
30.375 + (30.375/2) = 45.5625
