Answer:
Some similaritys were they were both quizes everyone took and some differences are one was harder, students did better on 1 than te other and a similarity is they both effected a students grade.
Step-by-step explanation:
Hi there!
The answer is B.
the cost of the game.
We need to know the cost of the game in order to find out how many weeks John has to save money. If we don't know this price, we'll never know whether John has saved enough money.
We can find out the total amount of money John can save in 1 week (so A. is not the answer). The amount of money John earns per hour doesn't matter to answer the question (so C. is wrong).
~ Hope this helps you!
Answer:
i don't what you want me to do here...
You gave me the same problem just two different numbers so maybe the answer is 7... idek tho bro
k times x = 7
k times x = 49
Step-by-step explanation:
7x-5<13x-3
Minus 7x
-5<6x-3
then add 3
-2<6x
Then divide -2 by 6 and 6x by 6
-1/3>x
I think thats right
Answer:
t=2
j=1
Step-by-step explanation:
3 tacos and a juice is $7
3t+j=7
4 tacos and 2 juices is $10
4t+2j=10
We have a simultaneous equation. It can be solved either by substitution method or Elimination method. For the purpose of this question, the elimination method will be used
3t+j=7 Equation 1
4t+2j=10 Equation 2
To eliminate j, we multiply Equation 1 by 2, the coefficient of j in equation 2, so that in both equations, j can have the same coefficient.
2(3t+j=7)
6t+2j=14 Equation 3
We now have
4t+2j=10 Equation 2
6t+2j=14 Equation 3
We subtract equation 2 from equation 3, to eliminate j
6t-4t=2t
2j-2j=0
14-10=4
We have 2t=4
Divide both sides by 2
2t/2=4/2
t=4/2
t=2
Substitute t for 2 in equation 1, to get j
3t+j=7
3(2)+j=7
6+j=7
j=7-6
j=1
One taco cost $2 while 1 juice cost $2
