Answer:

Option B) The simplification performed in step 2 is invalid or incorrect

The value of w in the given expression is -54

Step-by-step explanation:

Option B) The simplification performed in step 2 is invalid or incorrect

The corrected steps are given below :

GIven expression is w+xy+3x^2=2 and x=2y

To find w when y=-2 :

Step 1: I first substitute y=-2 into x=2y yielding x=2(-2)

Step2: I simplify the expression resulting in x=-4

Step3: I substitute x=-4 and y=-2 into the given expression w+xy+3x^2=2 we get

w+(-4)(-2)+3(-4)^2=2

Step 4: I use order of operations to simplify and get

w+8+3(16)=2

w=2-56

Therefore w=-54

The value of w in the given expression is -54

den301095 [7]

Answer:

AB= 12.94ft, 108deg

ZY= 6.76ft 50deg

XY 3.05ft, 22deg

Pathway adds up to 22.95ft

Step-by-step explanation:

AB is base

Sides 8 feet each = isosceles. =8ft, 8ft, 12.94ft

Top angle is 36 degree = 36°.36°,108°

ZY is base

Sides 8 feet each = isosceles = 8ft, 8ft, 6.76ft

Top angle is 65° = 65° 65° 50 °

XY is base

Sides 8 feet each =isosceles =8ft, 8ft, 3.05ft

Top angle is 79° degree = 79°,79 °,22 °

Pathway means triangles in a row side by side = Product of 3 values = ? feet

12.94 +6.76 + 3.05 =22.95ft pathway

The ratio of John's money to Jimmy's money is 5:8. Jimmy spent 1/4
erma4kov [3.2K]

Answer:

a. $3600

b. 6:5

Step-by-step explanation:

Put the question into an equation:

8x - 1/4 x 8x = 5x + 450

(simplify before solving) 6x = 5x + 450

(solve) 6x-5x = 450

x = 450

This means that Jimmy had 8 x 450 $ to start with = 3600

you can check this by subtracting a quarter of 3600 from 3600 and also multiplying 450 by 5 and then obtaining their difference. You get 450!

Now ratio of new amounts:

Jimmy now has: $2700

John still has: $2250

so ratio is 2700:2250

simplify to 6:5

Hope this helps
