Answer:
-1
Step-by-step explanation:
-7/10+7/15+1/-20+-9/10+11/15+11/-20
= -7/10 + -9/10 + 7/15 + 11/15 + 1/-20 + 11/-20
= -16/10 + 18/15 + 12/-20
= -8/5 + 6/5 + -3/5
= (-8+6-3)/5
= -5/5
= -1
Answer:
16
Step-by-step explanation:
Since DF and BC are similar, their ratios are:
12:3
4:1
Since AB is similar to ED:
Substituting the ratio:
x:4
Hence, x = 16
Hence, AB = 16

If the ratio is 4:3:2 each part of that ratio has a value of:
216/(4+3+2)
216/9=24
Since A pays four parts,
A pays 4*24=£96
Step-by-step explanation:
A rational number can be written as a ratio a/b, where a & b are integers & b \neq 0. Rational numbers are terminating or repeating. The radical sign means "the positive square root of."
Example:
√144 = "the square root of 144" but indicates the positive square root of 144, which is 12

Answer: cup is $2.55
Saucer $0.55
Step-by-step explanation:
Cost of cup and saucer is $3.10
Let the cup be x
And saucer be y
I.e
X+y= 3.10......equation 1
Cup which is X is $2 more than the saucer
I.e x=2+y......equation 2
Substitute for X in equation 1
(2+y)+y=3.10
2+2y=3.10
2y=3.10-2
2y=1.10
Y=1.10/2
Y=$0.55
Substitute for y in equation 2
X=2+y
X=2+0.55
X=$2.55
Therefore
The cup is $2.55
The saucer is $0.55
