150 grams weighs more. The number of ounces converted to grams would be about 142 grams.
Answer:
8 Miles on Tuesday
Step-by-step explanation:
Jahden walked (12x + 5r - 8) - (7x -10r) = 5x + 15r - 8 miles on Tuesday.

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
-5x + 6y = 55
4x + 3y = 34
<u>Step 2: Rewrite Systems</u>
4x + 3y = 34
- Multiply everything by -2: -8x - 6y = -68
<u>Step 3: Redefine Systems</u>
-5x + 6y = 55
-8x - 6y = -68
<u>Step 4: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: -13x = -13
- Divide -13 on both sides: x = 1
<u>Step 5: Solve for </u><em><u>y</u></em>
- Define equation: 4x + 3y = 34
- Substitute in <em>x</em>: 4(1) + 3y = 34
- Multiply: 4 + 3y = 34
- Isolate <em>y</em> term: 3y = 30
- Isolate <em>y</em>: y = 10
Answer:
P = 90 cm
Step-by-step explanation:
Let the sides of a triangle are 3x,5x and 7x.
The difference between the longest side and the shortest side is 24cm i.e.
7x-3x = 24
4x = 24
x = 6
Sides are :
3x = 3(6) = 18 cm
5x = 5(6) = 30 cm
7x = 7(6) = 42 cm
Perimeter = sum of all sides
P = 18+30+42
P= 90 cm
Hence, the perimeter of the triangle is equal to 90 cm.
