Step-by-step explanation:
Hi there!
Given; y= 7
5y + 3x + 2y - 8x = -1
Simply keep the value of y in the equation and simplify it;
5*7 + 3x -8x +2*7 = -1
35 - 5x +14 = -1
-5x = -1-49
X= -50/-5
Therefore, X= 10.
Hope it helps!

In a triangle, two angles have measures of 45 degrees and 85 degrees. What is the measure of the third angle in this triangle?
Answer:
50 degrees
Step-by-step explanation:
All three angles in a triangle add up to 180 degrees. If you know the measure of two angles, add them together and subtract the sum from 180.
45+85=130. Then, subtract 130 from the total, or 180. 180-130=50. The measure of the third angle of the triangle is 50 degrees.
On Saturday, you bowl at Mar vista Bowl, where renting shoes costs $2 and each game bowled is $3.50. On Sunday, you bowl at Pinz where the shoe rental is $5 and each game bowled is $3.25. If you spent the same amount each day, how many games,g, were bowled?
Answer:
12 gamesStep-by-step explanation:
Let the number of games is g
Total cost at Mar Vista:
3.5g + 2Total cost at Pinz:
3.25g + 5Since same amount spent in both places, we have:
3.5g + 2 = 3.25g + 53.5g - 3.25 = 5 - 20.25g = 3g = 3/0.25g = 12Answer:
12
Step-by-step explanation:
Let the game be x
3.5x + 2 = 3.25x + 5
3.5x - 3.25x = 5 - 2
0.25x = 3
x = 3/0.25
x = 300/25
x = 12

What is sum of two numbers?In mathematics, summation exists the addition of a series of any kind of numbers, named addends or summands; the result is their sum or total.
A sum exists as the result of an addition. For example, adding 1, 2, 3, and 4 provides the sum of 10, written. (1) The numbers being summed are named addends, or sometimes summands.
A summation, also named a sum, is the outcome of arithmetically adding numbers or quantities. A summation always includes a whole numeral of terms. There can be as irregular as two terms, or as many as a hundred, a thousand, or a million. Some summations include infinitely many terms.
Let the number be x and y,
ATQ, 6(x+y)=324 and
x-y=90, x+y=56 and

The amount of motor oil used during the month by the local stock car racing team is g(t) hundred gallons, where t is the number of months past March of a given year.
(a) Write a sentence of interpretation for
g(4) = 13.10.
The answer is "The local inventory car racing team used 1310 gallons of engine oil in July".
The function consists of 3: input, output, as well as the relationship between the two.The interpretation of a mathematical formalism is to derive important data from a line chart or given symbolic image.Therefore, the amount of oil that the regional sports car racing team is using during the month is G(t), which is 100 gallons, wherein T is the number of months that very last March.Given:
[tex]\to \bold{g(4) = 13.10}[/tex]
If [tex]\bold{g(4)=13.10}[/tex] means that [tex]\bold{1310 }[/tex] gallons of motor oil was used by the local stock car racing squad in July.So, the final answer is "The local inventory car racing team used 1310 gallons of engine oil in July".Learn more:
