Assume the old of Jack is X and the old of Lacy is Y
so ...
do the mathematical model ...
.
X=2Y
(X+7)+(Y+7)= 35
-
THEN
Solve the equation
y= 7
x = 14
Let's solve for y.
4x+7y=28
Add -4x to both sides.
4x+7y+−4x=28+−4x
7y=−4x+28
Divide both sides by 7.
7y/7=−4x+28/7
y=−4/7x+4
Answer:
Question 1: 76 dollars. ($76)
2. 1/5
3. 1/19
4. 1/5
Step-by-step explanation:
QUESTION 1:
228 (the amount Mrs. Nicci had) divided by 3 (children) is equal to 76
228/3 = 76
QUESTIONS 2, 3, AND 4.
2. Find the greatest common divisor (GCD). the GCD of 14 and 70 is 14. Then, divide the numerator and denominator by 14.
14/14 = 1
70/14 = 5
WHICH EQUALS 1/5!!
3. Find the greatest common divisor (GCD). the GCD of 5 and 95 is 5. Divide both the numerator and denominator by 5.
5/5= 1
95/5= 19
WHICH EQUALS 1/19!!
4. Find the greatest common divisor (GCD). the GCD of 12 and 60 is 12. So (like we have been doing for the whole part of this question), divide both the numerator and denominator by 12, which is the GCD.
12/12 = 1
60/12 = 5
WHICH EQUALS 1/5!!
Hope this helped.. I think this is like one of the longest Brainly answers I've recently had to type lol
Answer:
1/3
Step-by-step explanation:
There are 6 possible outcomes when rolling 1 die
1,2,3,4,5,6
P ( 1 or 5) = number of times 1 or 5 happens / total outcomes
= 2/ 6
= 1/3
Answer:
so to get a third you divide it by 3
first convert it to fraction
so it is 26/3
so do 26/3 divided by 3
so we do keep switch flip
26/3*1/3
so answer is 26/9 or 2 8/9
Step-by-step explanation:
