6, w, plus, 10
6w+10
Answer
Attempt 1 out of 2
To find the value of the expression 6w+10 when w equals 9, substitute 9 for w in the expression:
6w + 10 = 6(9) + 10
Multiply 6 and 9: 54
Add 54 and 10: 54 + 10 = 64
Therefore, the value of the expression 6w+10 when w equals 9 is 64.
What is the value of the expression below when w, equals, 3w=3 and x, equals, 3x=3?
10, w, plus, 5, x
10w+5x
Answer
Attempt 1 out of 2
To find the value of the expression 10w + 5x when w equals 3 and x equals 3, substitute 3 for w and 3 for x in the expression:
10w + 5x = 10(3) + 5(3)
Multiply 10 and 3: 30
Multiply 5 and 3: 15
Add 30 and 15: 30 + 15 = 45
Therefore, the value of the expression 10w + 5x when w equals 3 and x equals 3 is 45.
What is the value of the expression below when w, equals, 3w=3?
3, w, squared, minus, 6, w, minus, 4
3w
2
−6w−4
Answer
Attempt 1 out of 2
To find the value of the expression 3w^2 - 6w - 4 when w equals 3, substitute 3 for w in the expression:
3w^2 - 6w - 4 = 3(3)^2 - 6(3) - 4
Evaluate 3^2 = 9: 3(9) - 6(3) - 4
Multiply 3 and 9: 27 - 6(3) - 4
Multiply 6 and 3: 27 - 18 - 4
Subtract 18 from 27: 9 - 4
Subtract 4 from 9: 5
Therefore, the value of the expression 3w^2 - 6w - 4 when w equals 3 is 5.
