First make the denominators the same = 4 5/20 - 3 12/20. Then make them improper fractions= 85/20-72/20= 13/20. Since that is already simplified the answer is 13/20.
Answer: 20%
Step-by-step explanation:
To find the total number of problems Emilia solved, we can first add 19 and 76 to get:
19 + 76 = 95
Next, to find how many problems Emilia got correct out of the total, we can use the number of problems correct (19) and divide it by the total number of problems (95) to get:
19 ÷ 95 = 0.2
Finally, to make 0.2 a percentage, we can multiply it by 100 to get:
0.2 X 100 = 20
Therefore, Emilia got 20% of the problems correct.
Answer: Diego, 4a + 9b is equivalent
Step-by-step explanation:
7a + 5b - 3a + 4b
= (7a - 3a) + (5b + 4b) We rerange the variables, and put them together with (), which make it more clear to solve.
= 4a + 9b
Here, Equation: 4x + 2y = 4
Divide the equation by 2,
2x + y = 2
y = -2x + 2
Now, compare the equation with y = mx + c
Here, slope (m) = -2
In short, Your Answer would be -2
Hope this helps!
Answer:
6
Step-by-step explanation:
so this is (base times hight)
(bH)
42=7x
you didvide 7 from both sides
42 divided by 7 is 6
so basically its 6
because that would be your base thats what you are missing
then its just baseically (BH) (7 times 6)= 42
if this is wrong im so sorry I just learned this good luck
