Answer:
digits are: 0, 4, 8. The required number is: 480.
Step-by-step explanation:
→ Let ones digits is 'x', then according to the condition the hundreds digit is 'x+4', and the tens digit is '2(x+4)'.
→ According to the condition the sum of the digits is: x+(x+4)+2(x+4)=12.
→ After evaluation this equation, x=0 - this is ones digit;
→ x+4=0+4=4 - this is hundreds digit;
→ 2(x+4)=2(0+4)=8 - this is ten digit.
t = 15 + x and t = 5 + 2x represents the system of equations for this real world situation
<em><u>Solution:</u></em>
<em><u>Workout Gym has a sign up fee of $15 and charges $1 per day for membership</u></em>
Therefore,
Sign up fee = $ 15
Charge per day = $ 1
Let "x" be the number of days charged for membership
Let "t" be the total charge for membership
<em><u>Thus, we frame a equation as:</u></em>
Total fee = sign up fee + charge per day (number of days)
Total fee = 15 + 1(x)
t = 15 + x ------- eqn 1
<em><u>Healthy Gym has a $5 sign up fee and charges a $2 daily fee</u></em>
Sign up fee = $ 5
Charge per day = $ 2
Let "x" be the number of days charged for membership
Let "t" be the total charge for membership
<em><u>Thus, we frame a equation as:</u></em>
Total fee = sign up fee + charge per day (number of days)
t = 5 + 2(x)
t = 5 + 2x ------- eqn 2
Thus eqn 1 and eqn 2 represent the system of equations for this situation
Answer:
4(5 - 7x) = 6 - 12
20-28x=6-12x
Subtract 20 from both sides
20-28x-20=6-12x-20
Simplify
-28x=-12x-14
Add 12x to both sides
-28+12x=-12x=-12x-14+12x
Simplify
-16x=-14
Divide both sides by -16
-16/-16 = -14/-16
Anw
7/8= 0.875
Answer:2
Step-by-step explanation: because a square has four sides, and you just divide 8 by the amount of sides, which is 4. So 8/4=2
Hi!
These two angles are alternate interior angles, so they are congruent. Thus:
∠A = ∠B
6x + 5 = 4x + 45
Solve for x:
2x + 5 = 45
2x = 40
x = 20
Solve for ∠A by substituting in this value:
∠A = 6(20) + 5 = 125°
