b)

|2x−3y| if x=0.5; y=−0.7

Substitute: |2(0.5)-3(-0.7)|

Simplify: |1+2.1|

Simplify: |3.1|

Since it is an absolute value, it will always be positive: 3.1

d)

|−3 |x| +2x−1| if x=−5

Substitute: |-3(|-5|)+2(-5)-1|

Absolute value is positive: |-3(5)+5(-5)-1|

Simplify: |-15-25-1|

Simplify: |-41|

Absolute value always positive: 41

Given 3x + y =17 and x+3y = -1 find the value of 3x + 3y
Phoenix [80]
3x+y=17
=> 3x=17-y
Again, x+3y=-1
=> 3y= -1-x
now, 3x+3y= (17-y)+(-1-x)
                  = 17-y-1-x
                  = 16-x-y

Can someone offer help to this ratio question
AlekseyPX

Answer:

Cherry Pink has not been made (25:17\neq 4:3)

Step-by-step explanation:

Given that she already has 60litres of Rose Pink paint, we use the ratios to determine the volumes of red/white used:

Rose Pink=60l\\\\Red=\frac{1}{3}\times 60\\\\=20l\\\\White=\frac{2}{3}\times 60\\\\=40l

#Add these proportions to the additional red and white paints to determine if Cherry Pink has been made:

V_r=20l+80l\\\\=100l\\\\V_w=40l+28l\\\\=68l\\\\\therefore r:w=100l:68l     \ \ \ \ \  \ \ \ \  \ \# simplify\\\\r:w=25:17

We equate this proportion to the Cherry Pink proportion to verify if Cherry pink has been made:

25:17\neq 4:3

Hence, Cherry pink has not been made.
