Answer:

67

Step-by-step explanation:

We are given the expression:

wx+4

and asked to evaluate when w=9, x=7, and y=1.

The expression does not contain the variable y, so we can disregard it.

However, the expression does have the variable x and w. We can substitute 9 in for w and 7 in for x.

(9)(7)+4

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

First, multiply 9 and 7.

9*7=63

63+4

Next, add 63 and 4.

67

The expression wx+4 when evaluated for w=9 and x=7 is equal to 67.

Daniel created an intersection with his race track. One of the angles at the intersection is 55°. What are the three other angle
melomori [17]

Answer:

55, 125 and 125

Step-by-step explanation:

In this question, we are asked to find the other 3 angles in an intersection.

Please check attachment for what the diagram of the intersection might look like.

The intersection consists simply of 4 angles meeting at a point with the 2 angles on each side vertically opposite to the angles on the other side.

since one of the angles is 55, and we are having a straight line, the other angle would be 180-55 = 125.[ sum of angles on a straight line is 180]

These two angles are vertically opposite, this means that the other three angles are 55,125 and 125.
