Hello :
<span>2x+4y=38 ...(1)
10x+3y=105....(2)
-10x-20y = - 190
10x+3y =105
add : -17y = - 85
y = 5
subsct in (1) : 2x +20 =38
2x = 18
x=9

Answer:
There are 60 6th graders in band.
Step-by-step explanation:
Let x represent the number of 6th graders in band. If there are 25% more in 7th grade, you can write it as (5/4)x. (You could also say 1.25x, but I think fractions would be easier in this situation.) Set up an equation:
x+(5/4)x=135
Now solve for x.
(4/4)x+(5/4)x=135
(9/4)x=135
(1/4)x=15
x=60
There are 60 6th graders in band.
Hope I could help you!
Answer:An integer is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 512, and √2 are not. ( means Whole in Latin ) please give brainliest if possible
<span>Subtract u from 7, then divide v by the result</span>
v : (7 - u)
First plug in the numbers: 3x6+4x12/2. then do the Pemdas, so multiplication first: 18+42/2. then since the division is like a fraction bar, it means to divide but first simplify the 18+42: 60/2. Your answer is 30.
