Answer:
n=7
Step-by-step explanation:
7 times 5 equals 35.
Answer:
4(x+x+1+x+2)=132
4(3x+3)=132
4×3(x+1)=132
12(x+1)=132(dividing 132/12)
×+1=11
x=11-1
x=10
Mari and Kai's test scores are shown below: Mari: 72, 80, 90, 73, 74, 90 Kai: 56, 63, 70, 100, 32, 23 If Kai and Mari both got a
mezya [45]
Answer:
A. Kai
Step-by-step explanation:
1st Step - find the average test scores for Mari and Kai
1st Step - find the average test scores for Mari and Kai
Mari: 72 + 80 + 90 + 73 + 74 + 90 = 479
479 ÷ 6 (total number of tests) = 79.8 (Average test score for Mari)
Kai: 56 + 63 + 70 + 100 + 32 + 23 = 344
344 ÷ 6 (total number of tests) = 57.3 (Average test score for Kai)
2nd Step - Now each student got a 100 on the next test (the 7th test). So add 100 to the initial total.
Mari: 479 + 100 = 579
579 ÷ 7 (new total number of tests) = 82.7 (New average test score for Mari)
Kai: 344 + 100 = 444
444 ÷ 7 (new total number of tests) = 63.4 (New average test score for Kai)
3rd Step - find the difference between Mari's test scores. then find the difference between Kai's test scores to see who will have the greatest increase in math grade.
Mari: 82.7 - 79.8 = 2.9
Kai: 63.4 - 57.3 = 6.1
6.1 is greater than 2.9
Answer:
a) $37.387
b) $1,588.95
Step-by-step explanation:
Hi, to answer this question, first, we have to multiply the last paycheck
(106.82) by the percentage saved in decimal form (divided by 100)
a) 106.82 x (35/100) = $37.387 (weekly saving)
Now, we have to multiply that result by the number of weeks.
b) 37.387 x 42.5 =$1,588.95
