The least common multiple of 3, 4, 6, and 8 is 24.
List the multiples out:
3: 3, 6, 9, 12, 15, 18, 21, 24
4: 4, 8, 12, 16, 20, 24
6: 6, 12, 18, 24
8: 8, 16, 24

Answer: t = 340+22-10
Step-by-step explanation:
Hi, to answer this question we have to analyze each runner:
Norma takes 340 seconds to run the course.
Norma's time = 340
Jeremy takes 22 seconds longer to run a particular course than Norma. Since he takes seconds longer, we have to add that amount to Norma’s time:
Jeremy's time = Norma's time +22 = 340+22
Eleanor is a faster runner than Jeremy by more than 10 seconds. Since she is faster, we have to subtract 10 seconds to Jeremy's time to obtain Eleanor's time (t)
t = Jeremy's time - 10
t = 340+22-10 (seconds)
You have to multiply everything inside the parentheses by 5.
So it will look like this
5z+10
Answer:
x = -1
y = 5
Step-by-step explanation:
x+y=4
3x+7y=32
<em><u>To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.</u></em>
x+y=4,3x+7y=32
<em><u>Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.</u></em>
x+y=4
<em><u>Subtract y from both sides of the equation</u></em>.
x=−y+4
<em><u>Substitute −y+4 for x in the other equation, 3x+7y=32.</u></em>
3(−y+4)+7y=32
<em><u>Multiply 3 times −y+4.</u></em>
−3y+12+7y=32
<em><u>Add −3y to 7y.</u></em>
4y+12=32
<em><u>Subtract 12 from both sides of the equation</u></em>.
4y=20
<em><u>Divide both sides by 4</u></em>.
y=5
<em><u>Substitute 5 for y in x=−y+4. Because the resulting equation contains only one variable, you can solve for x directly.</u></em>
x=−5+4
<em><u>Add 4 to −5.</u></em>
x=−1
