Answer:
10x - 12y = 192
Step-by-step explanation:
Given the equation :
-5/8x + 3/4y = 12 - - - (1)
8x + 12y = 11 ___(2)
The equivalent form of the first equation which can eliminate the y term :
Multiply (1) by - 16 :
-5/8x * - 16 + 3/4y * - 16 = 12 * - 16
10x - 12y = 192
Hence, Adding the obtained equation and equation(2) will eliminate.

Lottie and Ollie shared some money in the ratio 5:1.
Ollie received £15.
How much did Lottie receive?
Answer:
=£75
Step-by-step explanation:
ratio=5(lottie):1(Ollie)
we do 15/1 which will stay the same as 15
15/1=15
Then we times 15 by 5( lotties share)=75
15*5=75
Therefore lottie got £75
=£75
Answer:
75 : 15

Select the correct answer from each drop-down menu. Describe the relationship between the area of a circle and its circumference. The (area, diameter, or radius) is (1/3, 1/2, 2, or 3) times the (area, diameter, or radius) times the circumference. (PLEASE HELP ME)
Answer:I got the answer correct because i have to take the test
Step-by-step explanation:
The relation between the area and the circumference is given by:
"The area is 1/2 times the radius times the circumference".
How to find the measures of a circle?
We know that for a circle of radius R we have:
Circumference = P = 2*pi*RArea = A = pi*R^2.If you take the quotient between the area and the circumference, you get:
A/P = (pi*R^2)/(2*pi*R) = R/2
So the area is R/2 times the circumference, or, using the terms given in the list:
"This means that the area is 1/2 times the radius times the circumference"

A bus averages 2miles per hour faster than a motorcycle. If the bus travels 165miles in the same time it takes the motorcycle to travel 155miles, then what is the speed of each?
Answer:
speed of bus = 33 mi/hr
speed of motorcycle = 31 mi/hr
Step-by-step explanation:
Let the speed of the motorcycle be x mi/h.
Now, we are told that the bus averages 2 mi/hr faster than the motorcycle. Thus, speed of bus = (x + 2) mi/hr
Formula for time is; t = distance/speed
Since distance covered by bus is 165 miles, then t_bus = 165/(x + 2)
Since distance covered by motorcycle is 155 miles, then t_motorcycle = 155/x
We are told that the bus and the motorcycle used the same time to cover their respective distances. Thus;. t_bus = t_motorcycle
Thus;
165/(x + 2) = 155/x
Cross multiply to get;
165x = 155(x + 2)
165x = 155x + 310
165x - 155x = 310
10x = 310
x = 310/10
x = 31 mi/hr
Then speed of bus = 31 + 2 = 33 mi/hr

Please I need quick help, Solve for X
Answer:
10
Step-by-step explanation:
Since it's a right angle, it's already 90 degrees. So, you add 48 + 32 which gives you 80. 80 minus 90 equals 10.
48 + 32 = 80
90 - 80 = 10

Suppose that appoximately 261,000,000 people live in the united states. Of these people 37,600,000 speak a language other than english at home who speak another lanague at home over 45 percent speak spanish
Answer:
16,920,000 people speak Spanish at home in the United States, which represents 6.48% of the country's population.
Step-by-step explanation:
Given that approximately 261,000,000 people live in the United States, and of these people 37,600,000 speak a language other than English at home, of which over 45 percent speak Spanish, to determine the number of people who speak Spanish in the United States, the following calculation has to be done:
37,600,000 x 0.45 = X
16,920,000 = X
261,000,000 = 100
16,920,000 = X
16,920,000 x 100 / 261,000,000 = X
6.48 = X
Thus, some 16,920,000 people speak Spanish at home in the United States, which represents 6.48% of the country's population.
