Answer:
Microscopes cost $44 and Dissection Kits cost $11
Step-by-step explanation:
Using the information given, we can make the system of equations:
30x+48y=1848
x represents the price of microscopes and y represents the price of dissection kits.
We also know that microscopes will be 4x the price of dissection kits. Therefor:
x=4y
We can plug these two equations together to find the answer.
30(4y)+48y=1848
120y+48y=1848
168y=1848
y=11
Using the y-value, can find the x-value.
x=4(11)
x=44
<span>10/9, or 1 1/9 lbs of walnuts.
The original ratio of walnuts to fruit is (2/3)/(3/5) and we wish to retain that ratio. So let's set up an equality to express that.
(2/3)/(3/5) = X/1
Now solve for X.
(2/3)/(3/5) = X/1
(2/3) * (5/3) = X/1
10/9 = X/1
10/9 = X
So we need 10/9 pounds of walnuts.</span>
Answer:
length and width of the photo are: w = 6cm l = 8cm
Step-by-step explanation:
Area = 168cm^2
Area = w • l
168 = (x + 3 + 3) • (x + 2 + 3 + 3)
168 = (x + 6) • (x + 8)
expand
168 = x^2 + 14x + 48
subtract 168 from both sides
0 = x^2 + 14x - 120
simplify
0 = (x - 6) • (x + 20)
x = 6 or -20
since we are dealing with a measurement of a physical object x > 0
x = 6cm
w = x = 6cm
l = x+2 = 8cm
Answer:
-5 = x
Step-by-step explanation:
First you begin with adding 5 to the other side of the equal sign.
Why? because you want to get "x" by itself, in other words, isolate the variable. and by adding 5 you make 0 on that side
So -10+5 = 5
Therefore -5 = x
<span>Taylor Street.
I am assuming that the Lombard street is the famous Lombard street in San Francisco, California. With that assumption, after going East 3 blocks, you'll reach the intersection of Lombard and Jones. After going south 2 blocks, you'll reach the intersection of Jones and Filbert. Finally, after turning left and going 1 block, the first intersection will be Taylor Street.</span>
