Multiplication because 10x10 writes 10,
10 times
First, minus the amount of children in cars from 258
258-13=245
Next:
245/7=35.
Answer: 35 kids on each bus.
Hope this helps. May I have brainliest please? :))))
Answer:5
That is exactly correct! Just two things: First, tan,sin,cos, etc hold no meaning on their own, they need an argument. So just be sure to write tanx, cosx etc rather than just tan or cos.
Finally, you could save time on your proof by noticing on the fourth step that
1cosxsinx=1cosx1sinx=secxcscx

Answer:
x = 23/5 and y = 7/20
Step-by-step explanation:
2x + 8y = 12 and 3x - 8y = 11 are two given equations
Now,
<u>Step </u><u>1</u><u>:</u>
2x + 8y = 12 ...(1)
3x - 8y = 11 ...(2)
<u>Step </u><u>2</u><u>:</u>
From equation (2) we get the value of x
i.e.,
3x - 8y = 11
3x = 8y + 11
<em><u>x = 8y + 11/3</u></em>
<u>Step </u><u>3</u><u>:</u>
Now,
Put the value of <u>x = 8y + 11/3</u><u> </u>in equation (1) we get,
i.e.,
2x + 8y = 12
2(8y + 11/3) + 8y = 12
16y + 22/3 + 8y = 12
16y + 22 + 8y(3)/3 = 12
16y + 22 + 24y/3 = 12
16y + 24y + 22 = 12 * 3
40y = 36 - 22
40y = 14
y = 14/40
<em><u>y = 7/20</u></em>
<u>Step </u><u>4</u><u>:</u>
Now,
Substitute the value of <u>y = 7/20</u><u> </u>in equation (2) we get,
i.e.,
3x - 8y = 11
3x - 8(7/20) = 11
3x - 56/20 = 11
3x - 14/5 = 11
3x = 11 + 14/5
3x = 11 * 5 + 14/5
3x = 55 + 14/5
3x = 69/5
x = 69/3 * 5
<em><u>x = 23/5</u></em>
