Answer:
a) 2x+4
b)x=8
Step-by-step explanation:
a) x+x+4 =2x +4
b) 2x+4= 20
2x = 16
x=8
Jay bought 8 packets of Chips
c) Jay: 8 x 60
=£4,80
Lauren : 12 × 60
= £7,2
Answer: t < 4 hours
Step-by-step explanation:
Renting = $37 + t x $5.70
If $37 + t$5.70 < $59.80
t$5.70 < $59.80 - $37
t$5.70 < $22.80
t < $22.80/$5.70
t < 4 hours

Answer:
Step-by-step explanation:
<u>Division of fractions</u>
To calculate the division of fractions a/b and c/d, it's usually easier to multiply a/b by the reciprocal of the denominator, that is:
We will evaluate x/y when x=9/4 and y=3/5:
Simplifying:
C. 3 and 7 because corresponding angles are congruent when an transversal intersects the line
So, the way to find the slope from points is (y2-y1)/(x2-x1) (x1,y1) and (x2,y2)
So, we'll take the second coordinates, which was (2,3). This means that x2 is 2 and y2 is 3.
The first coordinates are (4,-1), meaning x1 is 4 and y1 is -1. Now lets plug that into our formula
(y2-y1)/(x2-x1) x1=4, y1=-1 x2=2, y2=3
(3-(-1))/(2-(4))
(3+1)/(2-4)
4/-2
-2
So, the slope is -2
