Answer: -1 and 1
Step-by-step explanation:
Let the first integer be x and the second x +2 , clearly, the larger is x + 2.
From the statement given
x + 2 = 3x + 4
x - 3x = 4 - 2
-2x = 2
x = -1
The second integer is -1 + 2 = 1
Option B is the correct answer.
3 is greater than -5, -9, and -1.
Hint: Remember to distribute the negative when solving. A negative directly outside outside of and to the left the parenthesis times a negative number inside the parenthesis makes that number positive.
So for option B, you can simplify it to -3 +4 +2. And that equals 3.
A) -3+-4-(-2) = -5
B) -3-(-4)-(-2) = 3
C) -3+(-4)-2 = -9
D) -3-(-4)-2 = -1
Answer:
5.23×10^5
Step-by-step explanation:
You mean 56.23×10^4?
That would be 5.623×10×10^4, or 5.23×10^5
Answer:
Jelly beans: $6 for 1 kg
Gummy worms: $7 for 1 kg
Step-by-step explanation:
In this question, we need to find the cost of 1kg of jelly beans and gummy worms.
To do this, make equations for both scenarios and solve:
2j + 2g = 26
2j + 3g = 33
Turn the bottom equation negative, as we will first solve for gummy worms (g).
2j + 2g = 26
-2j - 3g = -33
Solve:
-g = -7
Divide both sides by -1.
g = 7
We now know that gummy worms cost $7 for 1 kg
To solve for jellybeans (j), plug in 7 to g in one of the equations and solve:
2j + 2(7) = 26
2j + 14 = 26
Subtract 14 from both sides.
2j = 12
Divide both sides by 2.
j = 6
Jellybeans cost $6 for 1 kg.
Check answer by plugging in values to one of the equations:
2(6) + 2(7) = 26
12 + 14 = 26
26 = 26
