First add the fractions.
6/7 + 5/7 = 1 4/7
Then add the whole numbers
4 + 3 = 7
Then add the mixed number to the whole number
7 + 1 4/7 = 8 4/7
Your answer is 8 4/7
Ok so, this one is a confusing one for me but what I recomend is going on a website call desmos , they have a graphing area there and use y=-4x-7 if I’m right, I do not know so don’t trust me on this
The answer is:
940
----
70
Here's my work:
<span><span><span>949/70</span></span>=<span><span><span><span>70t/</span>70</span></span>
-</span></span>Cross-multiply.<span><span><span><span>
949/70</span></span></span>=<span><span><span><span>70t/</span>70</span></span></span></span><span><span><span>
(949)</span>*<span>(70)</span></span>=<span><span>70t</span>*<span>(70)
</span></span></span><span>66430=<span>4900t</span></span>
-Flip the equation.
<span><span>4900t</span>=66430</span>
-Divide both sides by
4900.<span><span><span><span><span>4900t
</span>4900</span></span></span>=<span><span><span>66430
4900</span></span></span></span><span>t=<span><span>94970</span></span></span>
Hope this helps:)
d $=d*100 cent
Let the unit cost of soda be p cents. So, unit cost of hot dog=2p cents
Total cost=cost of hot dog+cost of soda
or, 100d=h*2p+s*p=p(2h+s)
Or, p=100d(s+2h)p=100d(s+2h)
Answer:
a = 18.15
Step-by-step explanation:
Combine like terms on the left side of the equation first. Add 7 and 42, then subtract 32 from the answer you get, then subtract 32 from that answer. This is going by order of PEMDAS.
Remember PEMDAS: (numbers 3 & 4 and numbers 5 & 6 are solved from left to right)
- Parentheses
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
After combining like terms on the left side, you get -15. Now combine like terms on the right side of the equation by adding 14.3 and 7.
Get -2a alone by subtracting 21.3 from both sides.
Divide both sides by -2.
In this equation, a should equal .
