Answer:
A) 4x+3y=14
B) 3x-2y=2
We multiply equation A) by (2/3)
A) (8/3) x +2y = 28/3 then we add this to equation B)
B) 3x-2y=2
5 (2/3) x = 11 (1/3)
x = 2
A) 4 * 2 + 3 y = 14
A) 3y = 6
y = 2
Step-by-step explanation:
Answer:
y=-6
Step-by-step explanation:
Answer:
x = 9
Step-by-step explanation:
Corresponding sides are in proportion. That means that 
12x - 12 = 96
12x = 108
x = 9
By the way, the scale factor is 16/12 = 4/3
Answer:
Step-by-step explanation:
Given that: x
2
+6x+8
=x
2
+4x+2x+8, (split middle term)
=(x
2
+4x)+(2x+8), (group pair of terms)
=x(x+4)+2(x+4), (factor each binomials)
=(x+4)(x+2), (factor out common factor (x+4)
Hence factors of x
2
+6x+8 are (x+4)(x+2)
Answer: 63/100 and 0.63
Step-by-step explanation: To find the fraction and decimal that is represented by this model, we first need to count how many cubes are shaded in. In the diagram shown, 63 of the cubes are shaded in and there is 100 of the cubes in total. the fraction 63/100 cannot be reduced so that is our answer. Now, let's turn 63/100 into a decimal. To write 63/100 as a decimal, remember that the bar that separates the numerator and denominator of the fraction is a division bar in disguise. This means that we can divided 63 by 100 and we will get 0.63 which is the equivalent decimal.
