Answer:
Michelle purchased 70 tomato plants and 60 bell pepper plants.
Step-by-step explanation:
Lets create a system of equations. Lets substitute x for the amount of tomato plants and y for bell pepper plants.
x+y=130
1.50x+2y=225
Lets use the substitution method.
Isolate y.
y=130-x
Substitute 130-x for y in the second equation.
x1.50+2(130-x)=225
Use the distributive property.
1.50x+260-2x=225
Combine like terms.
-0.5x+260=225
Subtract 260 on both sides.
-0.5x=35 or 0.5x=35
Now divide both sides by -0.5. Remember that <u>dividing by a decimal or fraction actually multiplies by the reciprocal.</u> So 35 divided by 1/2 would equal 35 multiplied by 2/1.
x=70
Substitute x in the equation to solve for y.
1.50(70)+2y=225
Multiply.
105+2y=225
Subtract 105 on both sides.
2y=120
Divide both sides by 2 to isolate y.
y=60
<em>X is equal to 70 and y is equal to 60.</em>
Just to check,<u> substitute our known values for variables.</u>
1.5(70)+2(60)=225
Multiply.
105+120=225.
Add.
225=225. Its correct!
Hope this helps!
Answer:
56
Step-by-step explanation:
JT=CJ+CT
4×+2=8×+5+55
4×+2=60-2
-4×=58
x=58/-4
x=-29/2
x=-14.5
JT=4x+2=4(-14.5)+2=-58+2=-56
Answer:
An experimental study because it will give the most accurate results.
Step-by-step explanation:
The observational study could also be somewhat useful, but the most accurate results will come from an experimental study. You will test the difference in DNA, blood pressure, and such. Whilst, the observational study, you only can observe the effects from the outside. The sample studies mean nothing because you can't test both sides of the complete study.
