Answer:
3.5x10³
Step-by-step explanation:
7x10^5=700000
2x10^2=200
Divide both by 100
7000÷2=3500
divide by 1000 as standard form is less than 10
1000 is 10 cubed
3500÷1000 is 3.5
∴3.5x10^3 is answer
Answer:
x=6
y=3 i think
Step-by-step explanation:
becuase it looks like they were cutting the mesuments from the triangle so the y would equal 3, andx would be 6.
X represent the number of laps Marcy swam, 1 1/4x represent the number of times Toni swam.
20 + 0.80(1 1/4x) + 15 + 0.85x = 257
20 + x + 15 + 0.85x = 257
1.85x + 35 = 257
Required equation is 1.85x + 35 = 257
Answer:
B. x > -1
Step-by-step explanation:
Subtract the left side:
... 0 < -6(1 -x) -2(x-5)
... 0 < -6 +6x -2x +10 . . . . eliminate parentheses
... 0 < 4 +4x . . . . . . . . . . . collect terms
... 0 < 1 +x . . . . . . . . . . . . . divide by 4
... -1 < x . . . . . . . . . . . . . . . add -1. Matches selection B.
