Must do multiplication first....
-2/5 - 3/7 x 7/10
-2/5 - 21/70 (I'll reduce 21/70)
-2/5 - 3/10
Now you have to find a common denominator and subtract
-35/50 = -7/10......is what I get

NEED HELP ASAP PLEASE HELP ILL GIVE YOU BRAINLIEST
nadezda [96]

Answer:

E. 1d+0.015d

G. 1.015d

Step-by-step explanation:

A is incorrect, as it only shows the 1.5% raise. B is incorrect, since that would be a 15% raise. C and D are incorrect because it's impossible to add a number with a variable to one without a variable. E is correct because it properly adds 100% (the amount he made without the raise) and 1.5% (the raise) together. F is incorrect because again, it adds 15%. G is correct because it is the total amount he makes, with the raise. H is incorrect because again, it adds 15%.

Factor de 16x + 40y ecuacion
trasher [3.6K]
To factor the expression you need to find the greatest common factor of the terms. The greatest common factor (GCF) is the highest number that will be into both terms. Since there's nothing that will fit into both x and y, you'll only need to find the GCF of the coefficients.

16x + 40y   To start, list the factors of both numbers

16: 1, 2, 4, 8, 16
40, 1, 2, 4, 5, 8, 10, 20, 40

You can see that 8 is the highest number that will go into 16 and 40. So, you can pull the 8 out of the expression.

8(2x + 5y)

S12 for the series 1+2+4+8+
Maru [420]
S_{12}=1+2+4+8+\cdots+2048
S_{12}=2^0+2^1+\cdots+2^{11}
2S_{12}=2^1+2^2+\cdots+2^{12}

\implies S_{12}-2S_{12}=2^0-2^{12}
-S_{12}=1-2^{12}
S_{12}=2^{12}-1
S_{12}=4096-1=4095
