It is 7 cuz u - 2 and add 5 and 2-6=4+5=9-2=7
Note the place values:
9 ones place value
. (decimal point)
3 tenths place value
4 hundredths place value
8 thousandths place value
8 ten thousandths place value
You are solving for the tenth place value. Look at the digit directly right of the tenths place value. It is the hundredths place value, which is 4.
Note that when rounding, if the number next to what you are solving for, has a value of 5 or greater, you round up. If it has a value of 4 and less, you round down. In this case, it is a 4, so round down.
9.3488 rounded to the nearest tenth is 9.3
9.3 is your answer.
We have two unknowns from the equation therefore, two equations are needed. These equations are:
<span>
3x + y = 9
y = –4x +10
To solve for y, we first substitute the second equation to the first one.
</span>3x + –4x +10<span>= 9
</span><span>x = 1
We substitute the value of x to either of the equations and solve for y.
</span>y = –4(1) +<span>10
</span><span>y = 6
</span>
<span>First find how many grams are in 15.87kg and how many meters are in 30.48cm
15.87kg x 1000g/kg = 15, 870g
30.49cm x 1m/100cm = 0.3049m
Then, set up a proportion.
0.3049m/15, 870g = 1m/x g
Cross multiply to get..
0.3049x = 15, 870
Divide for x and there you are.</span>Source(s):Myself.1004 <span>· 8 years ago
