Answer:
Step-by-step explanation:
If this is in terms of angles, 4x+6 must be equal to 90 since it is half of the angle produced by a line (180°) So solving for 4x+6=90, x=21
Answer:
The answer is 44 inches.
Step-by-step explanation:
6×7 1/3 = 44
Answer: 9
Step-by-step explanation: Here, we have the expression <em>4x - 7</em> and we want to evaluate the expression when <em>x</em> is equal to 4.
To evaluate an expression, we simply plug the value
of the variable into the expression and solve.
So here, since <em>x</em> is equal to 4, we have 4(4) - 7.
4(4) is equal to 16.
So we have 16 - 7 which is equal to 9.
So the value of our expression when <em>x</em> is equal to 4 is 9.
Answer:
8.5% interest rate
Step-by-step explanation:
Principle: $4000
Interest rate: x
Time : 5 years
4000( 5 ) ( x ) = Interest
4000x = 1700/5
4000x = 340
x = 0.085 or 8.5% interest rate
<em>Check:</em>
8.5% x 4000 x 5
= 340 x 5
= 1700
