3x:8=7:2. This deals with adding, subtracting and finding the least common multiple. Overview; Steps; Topics Terms and ... Step 2 : x Simplify — 8 ... Two fractions are called equivalent if they have the same numeric value. For example : 1/2 ...
The answer is 2 7/12. To find the answer you first find the equal denominator of 1/2 and 3/4 which is 4 because if you multiply 2 by 2 it is 4, then you multiply the 1 (numerator) by 2 to get 2 which 1/2 is 2/4, then you add 2/4 and 3/4 which is 5/4 which is equal to 1 1/4. Then you make the denominator of 1 1/4 and 1 1/3 equal, the number that both can equal is 12. You multiply 1/4 by 3 and you get 3/12, then you multiply 1/3 by 4 to get 4/12. So now you can add 1 3/12 and 1 4/12 which is 2 7/12.
Answer:
g(x)=f(x)=12x
Step-by-step explanation:
Since f(x)=g(x) at two points x=−3,−1 , we can tell that g(x) passes through the two points (−3,-32),(−1,−12)
But if g (x)is linear, that means that its graph is a straight line.
And since there is only one way to draw a straight line through two points, there is only one answer for g(x) , and since f(x) is a straight line passing through those two points as well, g(x) has to be equal to f(x)
Answer:
Therefore, the burritos cost $3.50 each and the tacos cost $2.50 each.
I hope this helps!
Step-by-step explanation:
Let x denote the price of the burrito and y denote the price of the taco.
Note that two burritos and five tacos cost 2x + 5y and five burritos and two tacos cost 5x + 2y. Since, they cost $19.50 and $22.50, respectively:
2x + 5y = 19.5. . . . . . . . . . . . . . . . . . . . .(1)
5x + 2y = 22.5. . . . . . . . . . . . . . . . . . . . .(2)
Multiplying (1) by 5:
5(2x + 5y) = 5(19.5)
==> 10x + 25y = 97.5. . . . . . . . . . . . . . . . .(3)
Multiplying (2) by 2:
2(5x + 2y) = 2(22.5)
==> 10x + 4y = 45. . . . . . . . . . . . . . . . . . .(4)
Subtracting (4) from (3):
(10x + 25y) - (10x + 4y) = 97.5 - 45
==> 21y = 52.5
==> y = 2.5.
Substituting y = 2.5 in (4) gives:
10x + 10 = 45 ==> x = 3.5.
