Answer:
the number is 4
Step-by-step explanation:
Hello,I think I can help you with this
Step 1
convert into mathematical terms
let x the unknown number
three more: 3 +
twice the sum of 7 and a number:2(7+x)
is 25:=25
Hence
3+2(7+x)=25
Step 2
Now, solve for x
3+14+2x=25
17+2x=25
2x=25-17
2x=8
x=8/2
x=4
the number is 4
Do not hesitate to ask me if you have any concerns
Have a great day.
More means add so you add 3+ then you multiply 2 so now you have 3 + 2 x 7= 25 you can check it by doing 3 + 2= 5 x 7=25

The slope will be -3/4 To find slope you just place the change in y over the change in x. 2- -1=3 0-4= -4 The slope is -3/4 which is the same as before
Answer:
We need to distribute the values Hence [-4 0: 0 - 2 ] +[0 -3: 5 -4] X + [ 0 -3: 5 -4 ] = [19 -27 : 10 -24]
