First solve the X factors on the left side: 2.3x - 6.7x = -4.4x 9.43-4.4x=-0.3x Next bring the all the x terms to the same side by adding -4.4x to each side 9.43=4.1x Then divide each side by 4.4 9.43/4.4 X=2.14 I think this is the answer but have to ask what is the sign that goes between 9.43 and 2.3x? This can drastically change the answer. Your goal is to solve for x, you do this by combining like like terms and isolating the the x terms.

Community Gym charges a $50 membership fee and a $70 monthly fee. Workout Gym charges a $190
zepelin [54]

Answer:

14 month

Step-by-step explanation:

Lets create equations for these two gyms. I believe this is an algebra 1 problem.

Community Gym: y=70x+50

Workout Gym: y=60x+190

Because both gyms are equal to y, we can set them together and solve for x.

70x+50=60x+190

10x=140

x=14

You can find the cost by plugging in 14 into both of the equations. You get a cost of $1030 after 14 months

Therefore, after 14 months you will have paid the same amount for both gyms.

A car moves with an average speed of 45 miles/hour. How long does the car take to travel 90 miles? A. 2 minutes B. 2 hours C. 45
svlad2 [7]

We know that distance = rate(time). We need to solve for time here.

d = rt\\90 = 45t\\t = \frac{90}{45}\\t = 2


The car took 2 hours to travel 90 miles at a speed of 45 mi/hr

Which inverse operation would be used to verify the following equation 54 divide 9 = 6
madam [21]
<span>In the question "Which inverse operation would be used to verify the following equation 54 divide 9 = 6" the correct answer is 9 multiplied by 6 = 54. The inverse operation of division is multiplication. So to verify a division problem, we multiply the result of the division problem with the divisor to obtain the dividend.</span>

Answer:

An equation is 92 + 2x = 180.

The congruent angles each measure 44°.

Step-by-step explanation:

1. If two angles in a triangle are congruent and unknown, we can represent that as 2x. That means 92 + 2x = 180.

2. To find the measure of each congruent angle, x, we have to solve the equation above.

Step 1: Simplify both sides of the equation.

  • 2x + 92 = 180

Step 2: Subtract 92 from both sides.

  • 2x + 92 - 92 = 180 - 92
  • 2x = 88

Step 3: Divide both sides by 2.

  • \frac{2x}{2} = \frac{88}{2}
  • x = 44

x = 44 means that the congruent angles each measure 44°.
