Answer:
1.11
Step-by-step explanation:
1.03+0.08=1.11
Replace X in the equation with the values in the table and calculate:
2X-5:
2(-4) -5 = -8 -5 = -13
2(-2)-5 = -4-5 = -9
2(1)-5 = 2-5 = -3
2(3)-5 = 6-5 = 1
2(5)-5 = 10-5 = 5
Answer:
7.4 · 10^4
Step-by-step explanation:
For scientific notation, multiplication is pretty simple.
In this case, you would only multiply the "regular" number by 2.
(3.7 · 2) · 10^4
= 7.4 · 10^4
However, if it were asking about multiplying the number with something else in scientific notation, in addition to what we did above, you'd add together the exponents.
I hope this helped!
Answer:
train a weighs 177 and train b weighs 90
Step-by-step explanation:
train a weighs 87 more tons than train b but both combined is 267.
a + b = 267
267 - 87 = 180
divide by two to get the weight of train b
180/2 = 90
add the 87 to find the weight of train a
90 + 87 = 177
check
90 + 90 + 87 = 267
this is my first time answering a question, hope this helped :)
