What is the value of the expression below when w, equals, 4w=4?
3, w, plus, 4
3w+4
Answer
Attempt 1 out of 2
The expression is 3w + 4 and we are told that w = 4.
To find the value of the expression, we substitute w = 4 into the expression:
3(4) + 4
Simplifying, we have:
12 + 4
The value of the expression is 16.
What is the value of the expression below when y, equals, 8y=8?
2, y, minus, 3
2y−3
Answer
Attempt 1 out of 2
The expression is 2y - 3 and we are told that y = 8.
To find the value of the expression, we substitute y = 8 into the expression:
2(8) - 3
Simplifying, we have:
16 - 3
The value of the expression is 13.
What is the value of the expression below when y, equals, 5y=5?
2, y, plus, 7
2y+7
Answer
Attempt 1 out of 2
The expression is 2y + 7 and we are told that y = 5.
To find the value of the expression, we substitute y = 5 into the expression:
2(5) + 7
Simplifying, we have:
10 + 7
The value of the expression is 17.
What is the value of the expression below when w, equals, 8w=8 and x, equals, 6x=6?
10, w, plus, 10, x
10w+10x
Answer
Attempt 1 out of 2
We are given that w = 8 and x = 6.
The expression is 10w + 10x.
To find the value of the expression, we substitute w = 8 and x = 6 into the expression:
10(8) + 10(6)
Simplifying, we have:
80 + 60
The value of the expression is 140.
What is the value of the expression below when w, equals, 7w=7?
w, squared, plus, 3, w, minus, 10
w
2
+3w−10
Answer
Attempt 1 out of 2
The expression is w^2 + 3w - 10 and we are told that w = 7.
To find the value of the expression, we substitute w = 7 into the expression:
(7)^2 + 3(7) - 10
Simplifying, we have:
49 + 21 - 10
The value of the expression is 60.
To find the value of the expression 3w + 4 when w = 4, you substitute the value of w into the expression and simplify.
In this case, w is equal to 4, so you replace w with 4 in the expression:
3(4) + 4.
Next, you perform the multiplication first:
3 × 4 = 12.
So now the expression becomes:
12 + 4.
Finally, you perform the addition:
12 + 4 = 16.
Therefore, when w is equal to 4, the value of the expression 3w + 4 is 16.
