Answer:
0.550
Step-by-step explanation:
Answer:
(10, -5)
Step-by-step explanation:
Given system of equations is,
0.6x - 0.3y = 7.5
Divide this equation by 0.3
2x - y = 25 -------(1)
0.4x + 0.2y = 3
2x + y = 15 -------(2)
Now we subtract equation (2) from equation (1),
(2x - y) - (2x + y) = 25 - 15
-2y = 10
y = -5
From equation (1),
2x - (-5) = 25
2x + 5 = 25
2x = 20
x = 10
Therefore, (10, -5) will be the solution of the system of equations.
It is 2.4 x 2.5 which equals 6 the answer is 6
Answer: m<PQT=60 and m<PQS=4x+14
m<PQS and m<SQT are same
m<PQT = m<PQS + m<SQT = m<PQS + m<PQS = 2m<PQS
m<PQT = 2m<PQS
So m<PQS =
Plug in the given information and solve for x
4x + 14 =
4x + 14 = 30 (subtract 14 on both sides)
4x = 16 (Divide by 4 on both sides)
x = 4
The value of x is 4
Dividing both into this (15 x 32) below.
15=10+5
32=30+2 and both of the equations will give you the result of 4 partial products.
10x30=300
5x30=150
10x2=20
5x2=10
