Answer:
10 × ( ? + ? )
half a number:
→10×(x2+?) and 6: → 10 × ( x 2 + 6 )
is 8 : → 10 × ( x 2 + 6 ) = 8
10 ( x 2 + 6 ) = 8
Multiply out the bracket
5 x + 60 = 8 Subtract 60 from both sides 5 x = 58
Divide both sides by 5 x = 58 5
10 times: Subtract 60 from both sides
5 x = 58 Divide both sides by 5 x = 58 5
Step-by-step explanation:
but i'm confused- if you said "VERY EASY QUESTION", why couldn't you answer it since you said "very easy"- nvm-
x
=
58

The sum of:
(

)
2
and 6:

is 8 :
8
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
60
Subtract 60 from both sides
Divide both sides by 5
1/2 is the closest at .5
13/26 is 1/2
3/8 is . 375
11/32 is .344
ok the last option is for the middle one and I think the vocabulary one goes with the second one of the options sorry I dont know anything else
The two number are :
x = 1411
y = 1079
Let the two numbers = x and y
The sum of two numbers is 2490
x + y = 2490..... Equation 1
If 6.5 percent of one no. is equal to 8.5 percent of the other,
Hence:
6.5% of x = 8.5% of y
0.065x = 0.085y
Make x the subject of the Formula
x = 0.085y/0.065
x = 1.308y
We substitute 1.308y for x Equation 1
1.308y + y = 2490
2.308y = 2490
y = 2490/2.308
y = 1078.8561525
x = 2490 - y
x = 2490 - 1079
