Answer:
Step-by-step explanation:
a + d + m + r = 16
a = d + 3......d = a - 3
a = m + 2.......m = a - 2
m = r + 1.......r = m - 1.......r = (a - 2) - 1......r = a - 3
a + (a - 3) + (a - 2) + (a - 3) = 16
4a - 8 = 16
4a = 16 + 8
4a = 24
a = 24/4
a = 6 <==== andrew scored 6
d = a - 3.....d = 6 - 3.....d = 3 <=== danielle scored 3
m = a - 2......m = 6 - 2.....m = 4 <==== mel scored 4
r = a - 3......r = 6 - 3 ......r = 3.......renee scored 3
Answer:
Large Jar
Step-by-step explanation:
Large jar- 440g for £1.54
- Cost per gram for the large jar = £1.54 ÷ 440g =£0.0035 per gram
Small jar- 340g for £1.26
- Cost per gram for the small jar = £1.26÷ 340g =£0.0037 per gram
Since the cost per gram of the large jar is lower, <u>the large jar offers best value for money.</u>
Givens
x = -2
y = 3
z = - 2
Expression2x - 3y - z
Substitute and solve
2(-2) - 3(3) - (-2) Notice that the 3 has 1 minus and the 2 has 2 minus signs. That means the the -3*3 = - 9 and - -2 = 2
-4 - 9 + 2
- 13 + 2
-11
Answer: 1st Choice
We have to find slopes one by one.
#1
- Line passes through this.
#2
#3
- Not possible (Line passes through y axis as one co-ordinate is (0,1))
#4
#5
- Line doesnot pass through this.
