A family was driving from Reading, Pa to Reighley, NC for Thanksgiving. They left their house at 10:00 am. By 3:00 pm they had travelled 250 miles. If they continue travelling at
the same rate, how many miles, in total, will they have travelled by 4:15 pm?

Point r divides in the ratio 1 : 3. if the x-coordinate of r is -1 and the x-coordinate of p is -3, what is the x-coordinate of q? a. b. 3 c. 5 d. 6 e. -9

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?

Cos^2x+cos^2(120°+x)+cos^2(120°-x)i need this asap. pls me
