Answer:
14%
Step-by-step explanation:
Last year's score = 350
This year's score = 399
What was the percent of increase in Kenia's score
Percentage increase= (new score - old score) / old score × 100
= (399-350) / 350 × 100
= 49 / 350 × 100
= 0.14 × 100
= 14%
The percent of increase in Kenia's score is 14%
Answer:
Step-by-step explanation:
1. Given that: y = (5 x 9) + (1 x 9)
= 45 + 9
= 54
Using repeated reasoning;
y = (5 x 9) + (1 x 9)
factoring 9 in the equation, we have;
y = 9 (5 + 1)
= 9 (6)
= 54
2i. 7 x 6 = (5 x 6) + (2 x 6)
= (5 + 2)6
= 7 x 6
= 42
ii. 7 x 9 = (5 x 9) + (2 x 9)
= (5 + 2)9
= 7 x 9
= 63
iii. 7 x 7 = (5 x 7) + (2 x 7)
= (5 + 2)7
= 7 x 7
= 49
Therefore, the factors that Pam used repeatedly are 5 and 2.
3. 7 x 8 = (LX) + (LX)
= X(L + L)
Representing L and X by a number,
7 x 8 = (4 x 7) + (4 x 7)
= 7(4 + 4)
= 7(8)
= 7 x 8
= 56
Thus, the generalization is true.
<u /><em></em>let the age of jim be x
carla's age= x+5
tomy's age= 6+5+x
sum of their ages=31
x+x+5+x+5+6=3x+16=31
3x=31-16
=15
x=15 divided by 3
= 5
jim's age=5
carla's age=<u />10
tomy's ag<u>e = 16</u>
Answer:
3/5x = 15
multiply both sides by 5
This cancels out denominator of fraction =
3x = 75
x = 25
Answer:
y=130°
Step-by-step explanation:
180-(90+40)
180-130
50°
y=180°-50°
=130°
