Answer 1
Answer:

Answer:

x=7

Step-by-step explanation:

x+4 + 2x1+3x-2  =45

6x+3 =45

6x=42

x=7

7+4 = 11

14+1=15

21-2=19

11+15+19 = 45

15/40 in lowest term I need it so bad now

Answers


In order to reduce ANY fraction to lowest terms, find any common factors
of the numerator and denominator, and divide them both by it.  If they still
have a common factor, then divide them by it again.  Eventually, they won't
have any common factor except ' 1 ', and then you'll know that the fraction is
in lowest terms.

Do  15  and  40  have any common factors ?
Let's see . . .

The factors of  15  are  1,  3,  5, and  15 .
The factors of  40  are  1,  2,  4,  5,  8,  10,  20, and  40 .

Ah hah !  Do you see that ' 5 ' on both lists ?  That's a common factor.

So  15/40  is NOT in lowest terms.

Divide the numerator and denominator both by  5 :

       15 / 40  =  3 / 8

3  and  8  don't have any common factor except ' 1 '. 
So  3/8  is the same number as  15/40, but in lowest terms.
3/8 is the answer

Someone drove 20 miles in 24 minutes at this rate how many miles did they drive in 6 minutes

Answers

distance = rate * time (I will abbreviate as d = rt)
d = rt, so r = d/t 
r = 20mi/24min
= 0.833333 mi/min.

d = rt again for the new time
d = 0.8333333 mi/min * 6 min = 5 miles

A desert has both fruit and yoghurt insideAltogether the mass of the fruit and yoghurt is 175g
The ratio of the mass of the fruit to the mass of the yoghurt is 2:5
Which calculation will give the mass of the yoghurt?
175 divide 5 times 7 or 175 divide 7 times 5 or 175 divide 5 times 2 or 175 divide 7 times 2
What is the mass of the yoghurt (not the fruit and yoghurt - just the yoghurt, so it's not 175g)?

Answers

2\ (the\ mass\ of\ the\ fruit)\ :\ 5\ (the\ mass\ of\ the\ yoghurt)\n\n\ \ \ \Rightarrow\ \ \ (5)/(7) \ of\ the\ all\ mass\ is\ the\ mass\ of\ the\ yoghurt\n\n (5)/(7) \cdot 175\ g\ =5\cdot 25\ g=125\ g\n\nAns.\ 175\ divide\ 7\ times\ 5.\ \ The\ mass\ of\ the\ yoghurt\ is\ 125\ g.
