Mathematics
1 answer:
Elena-2011 [213]2 years ago
7 0

Answer:

14

Step-by-step explanation:

Since S is the midpoint of RT, then RS = ST

RS = RT - ST = (3x + 7) - (x + 7) = 3x + 7 - x - 7 = 2x

so we get that RS = 2x

but since RS = ST, and RS=2x & ST=x+7

then 2x = x + 7

       2x-x = 7

        x = 7

ST = x+7 = 7+7 = 14

P.S. Hope it makes sense. If you have any questions, feel free to ask them in the comments senction. I'll be happy to help. Have a wonderful day!

If someone helps me I’ll give brainless
Sunny_sXe [5.5K]

Answer:

128

Step-by-step explanation:

The two angles form a straight line so they add to 180

2m+62  + 3m +143 = 180

Combine like terms

5m+205=180

Subtract 205 from each side

5m+205-205=180-205

5m = -25

Divide by 5

5m/5 = -25/5

m = -5

We want to find the angle so we substitute the value of m into the the formula for the angle.

< RBM =3m +143 = 3(-5) +143 = -15+143 =128

The ratio of the ages of neeti &amp; yash is 4 : 3, the sum of their ages is 28 yrs. what is the ratio of their ages after eight
valina [46]
Let neeti age=n
and yash age = y
then n/y =4/3
so n=4y/3
similarly
n+y=28
putting value of n
4y/3+y=28
(4y+3y)/3=28
7y/3=28
y=28*3/7
y=4*3=12
so y=12
n=4y/3
n=4*12/3
n=4*4=16
so ages
yash=12
neeti=16
after 8 years
yash=12+8=20
neeti=16+8=24
neeti/yash = 24/20
neeti/yash =6/5

Simplify using the vertical method. (2k+3)(2k^2-4k-3)
GuDViN [60]
4k^3 - 8k^2 + 6k^2 - 12k - 6k - 9
Combine like terms... -8k^2+6k^2= -4k^2
-12k+6k=-6k
and leave 4k^3 and -9 alone because you don't have anything to combine it with so the equation is  4k^3 -4k^2 -6k -9
