Answer:
√2.37+ 3 √9 = √5. 3 is the last one
x+9 =+25
Step-by-step explanation:
(x+9)2= 25 This means x= 3.5 and the square root of x = √3.5 = 1.87 square root of 9 x 2 = √18 =4.24
We can also see 18+7 =25
√5.65 √5
this is 25 = 5 so it's the last one.
as 2.37+ 3 √9 = √5. 3
Answer:
x = 1, y = 10
Step-by-step explanation:
y = -5x + 15 --- Equation 1
2x + y = 12 --- Equation 2
Substitute y = -5x + 15 into Equation 2:
2x + y = 12
2x - 5x + 15 = 12
Evaluate like terms.
15 - 3x = 12
Isolate -3x.
-3x = 12 - 15
Evaluate like terms.
-3x = -3
Find x.
x = -3 ÷ -3
x = 1
Substitute x = 1 into Equation 2:
2x + y = 12
2(1) + y = 12
2 + y = 12
Isolate y.
y = 12 - 2
y = 10
(2+1)+3=2+(2+2)
Any two numbers that add to 4.
